# 1 Introduction

# 1.1 Product Overview

The NuPRO-860 single board computer is comprised of the ProCB-860, a PICMG 1.2 ePCI-X compliant full-size carrier board, and the EM-64 CPU module. It features a single Intel® Pentium® M processor with 1MB L2 cache in a 478-pin Micro-FCPGA package, and is validated with the Intel® 855GME chipset that supports 144-bit wide PC2100/2700 (266/333 MHz) ECC DDR DIMM up to a maximum of 2GB.

The EM-64 CPU module is a 112.4 x 94 mm embedded form factor CPU module that incorporates the 855GME Graphics Memory Controller Hub (GMCH) northbridge. By separating the northbridge and southbridge between the EM-64 CPU module and ProCB-860 carrier board, the NuPRO-860 is designed to facilitate speedy development of semi-custom designs.

The ProCB-860 carrier board is equipped with the Intel® 6300ESB I/O Controller Hub (ICH). It also includes common PC peripheral I/O interfaces such as serial and parallel ports, keyboard/mouse, Gigabit Ethernet, IDE, VGA, and AC '97 audio.

The ProCB-860 carrier board and EM-64 CPU module are connected by a proprietary high-speed interface that links the CPU and northbridge on the CPU module to the southbridge on the carrier board. It also connects the display signals such as analog RGB ,LVDS LFP and DVO signals from the northbridge to the ProCB-860.

The NuPRO-860 is designed to support the following operating systems: Windows 2000, Windows XP, and Red Hat Linux 7.x

PCI golden finger bus-B. Throughput of PCI bus interface is 132 MB/s; supports 44-bit addressing using DAC protocol

▶ Integrated IDE controller supports dual Ultra ATA 33/66/100 IDE channels; secondary IDE also supports a DB-6760CF daughter card interface to provide one CF Type I/II connector.
▶ Integrated Serial ATA Host Controllers: Features two sets of interface signals that may be independently enabled, tri-stated or driven low. An independent DMA controller supports each interface.
▶ One EHCI USB 2.0 Host Controller and two USB UHCI Host Controllers provide support for 4 USB 2.0 ports (two ports on the back panel, and two ports via onboard pin header. Over-current detection, USB legacy devices, USB devices boot feature supported on all USB ports.
▶ ACPI Power Management Logic Support.
▶ Enhanced DMA Controller, Interrupt Controller, and Timer Functions.
▶ System Management Bus (SMBus) Specification, v2.0 with support for $I^{2}C$ devices.
▶ Low Pin Count interface/Firmware Hub: The ProCB-860's System BIOS flash, the SST 49LF004A (4Mbit capacity), is compatible with the Intel® 82802 Firmware Hub device. BIOS write-protect function can be enabled/disabled in the BIOS option menu.
▶ Watchdog Timer: A 2-stage Watchdog Timer (WDT) is embedded on Hance Rapids and can be enabled/disabled via BIOS settings. Supports a selectable prescaler – approximately 1 MHz (1 us to 1 s) and approximately 1KHz (1 ms to 10 min). When the counter reaches the first preset value the WDT generates an IRQ, SMI, or SCI interrupt and loads the second preset value. When the counter reaches the second preset value it drives WDT\_OUT# low and resets the ProCB-860.

Other features of the ProCB-860 include:

The Intel® 82541GI single port Gigabit Ethernet Controller supports one gigabit Ethernet (GbE) port which is connected to the rear I/O panel. The 82541GI enables offloading of tasks such as TCP/UDP/IP checksum calculations from the host processor, handles all IEEE 802.3 receive and transmit MAC functions, and contains fully integrated PHY circuitry for 1000 Base-T, 100 Base-TX, and 10 Base-T (IEEE 802.3, 802.3u, and 802.3ab) applications, provides an integrated dual-port solution comprised of two distinct MAC/PHY instances, and appears as a multi-function PCI device.

▶ Hardware Monitor: The W83627HF monitors critical hardware parameters, including system and CPU voltages and temperature. All hardware health status can be accessed from the BIOS options menu, and runtime utilities. In addition, once the preset thresholds of hardware conditions are met, the W83627HF will alert the system or reset the system in critical situations.

# 3 Getting Started

This chapter gives a summary of what is required to set up an operating system using the NuPRO-860. Hardware installation and BIOS setup are also discussed. Note that the NuPRO-860 is shipped with CPU, and RAM preinstalled. Installation of the CPU and RAM are performed at the ADLINK factory and the procedures described in the following sections are for user reference. If the default configuration does not suit your application needs, contact a local ADLINK dealer for special configurations or OEM versions.

# 3.1 CPU Installation

The NuPRO-860 supports the Intel® Pentium® M processors. If the required CPU module is pre-installed when the product is received, this section may be skipped.

First remove the heatsink from the EM-64 CPU Module by removing the four screws as shown in Figure 3.1: Heat Sink Installation. Replace the screws to secure the EM-64 CPU Module to the carrier board.

The CPU socket is located on the EM-64 CPU Module as shown in Figure 3.2: CPU Installation below. Remove the CPU from its packaging and place it carefully in the CPU socket as shown. Be sure to align the gold triangle on the corner of the chip with the corner of the socket that is missing a pin. Press down gently on the chip to ensure that it is securely in place, and then use a small flathead screwdriver to rotate the CPU lock clockwise and lock the CPU into position.

# 3.2 Memory Installation

The NuPRO-860 CPU Module supports 200-pin PC2100/PC2700 registered/unregistered ECC DDR SDRAM up to 2GB maximum. Two memory sockets are located on the CPU Core Module (one on each side). If the required memory modules are pre-installed when the product is received, this section may be skipped.

At least one memory module will be installed in the upper DIMM slot of the NuPRO-860 when shipped. You can upgrade the amount of RAM by changing the existing memory module, or by adding a second SDRAM module. It is necessary to disassemble the NuPRO-860 's EM-64 CPU Module assembly to install an SDRAM module in either of the sockets, so we recommend that users have the required SDRAM installed professionally by ADLINK.

The following list of memory modules has been tested for compatibility with the NuPRO-860. The table outlines the combinations of memory modules that have been tested on the NuPRO-860.

# 5 Watchdog Timer

The operation of the NuPRO-860's Watchdog Timer is described in this chapter. An overview of the watchdog operation and features, as well as the programming procedure is provided to give the user an insight into the workings of the Watchdog Timer.

# 5.1 WDT Overview

The primary function of the Watchdog Timer is to monitor the NuPRO-860's operation and to generate an IRQ or to reset the system should the software fail to function as programmed. The major features of the Watchdog Timer are:

▶ Enabled and disabled through software control
▶ Armed and strobed through software control

The NuPRO-860's custom Watchdog Timer circuit is integrated into the south bridge 6300ESB and supports multiple modes: WDT and free-running. Free-running mode is a one stage timer and it will toggle WDT\_TOUT# after a programmable time. WDT mode is a two stage timer and its operation is described as follows:

# WDT Mode:

The two-stage Watchdog Timer (WDT) provides a resolution ranging from 1 micro second to 10 minutes. The timer uses a 35-bit down-counter. The counter is loaded with the value from the first Preload register. The timer is then enabled and starts counting down. The time at which the WDT first starts counting down is called the first stage. If the host fails to reload the WDT before the 35-bit down counter reaches zero the WDT generates an internal interrupt. After the interrupt is generated, the WDT loads the value from the second Preload register into the WDT's 35-bit down-counter and starts counting down. The WDT is now in the second stage. If the host still fails to reload the WDT before the second timeout, the WDT drives the WDT\_TOUT# pin low. The WDT\_TOUT# pin is held low until the system is reset.

Figure 5-1: WDT Block Diagram

# 5.2 Configuration Registers

The Intel® 6300ESB ICH WDT, appears to BIOS as PCI Bus 0, Device 29, Function 4, and has the standard set of PCI Configuration register. The following describes the configuration registers.

# Offset 10H: Base Address Register (BAR)

This register determines the memory base for WDT down-counter setting. It will be used to set Preload value 1 register, Preload value 2 register, General Interrupt Status register and Reload register.

# Preload Value 1 & 2 registers

These two registers are used to hold the preload value for the WDT timer. Its value will be automatically transferred into the down-counter every time the WDT enters the first and second stage. Preload Value 1 register is located at Base + 00H and Preload Value 2 register is located at Base + 04H. Only bit [19:0] are settable.

The register unlocking sequence is necessary whenever writing to the Preload registers. Instructions for writing a value into preload value 1 & 2 registers are as follows:

1. Write 80H to offset BAR + 0CH.
2. Write 86H to offset BAR + 0CH.
3. Write desired value to preload register. (BAR + 00H or BAR + 04H)

# General Interrupt Status Register

This register is at Base + 08H. Bit 0 is set when the first stage of down-counter reaches zero.

Bit 0 = 0 - No Interrupt

Bit 1 = 1 - Interrupt Active

NOTE: This bit is not set in free running mode.

# Reload Register

This register is at Base + 0CH. Write 1 to bit 8 will reload the down-counter's value. Following is the procedure of how to prevent a timeout.

1. Write 80H to offset BAR + 0CH
2. Write 86H to offset BAR + 0CH
3. Write a '1' to RELOAD[8] of the reload register

# Offset 60 - 61H: WDT Configuration Register

Bit 5 indicates whether or not the WDT will toggle the WDT\_TOUT# pin when WDT times out. (0 = Enabled, 1 = Disabled)

Bit 2 provides two options for prescaling the main down-counter. (0 = 1ms - 10min, 1 = 1us - 1sec)

Bit [1:0] allows the user to choose the type of interrupt desired when the WDT reached the end of the first stage without being reset. (00 = IRQ, 01 = reserved, 10 = SMI, 11 = Disabled)

NOTE: The WDT does not currently support SMI. IRQ uses APIC 1, INT 10 and it is active low, level triggered.

# Offset 68H: WDT Lock Register

Bit 2 is used to choose the functionality of the timer. (0 = Watchdog Timer mode, 1 = Free running mode) The free-running mode ignores the first stage and only uses Preload Value 2. In free-running mode it is not necessary to reload the timer as it is done automatically every time the down-counter reaches zero.

Bit 1 enables or disables the WDT. (0 = Disabled, 1 = Enabled)

Bit 0 will lock the values of this register until a hard reset occurs or power is cycled. (0 = unlocked, 1 = locked). The default is Unlocked.

# 5.3 WDT Programming Procedure

1. Make sure WDT\_TOUT# signal is enabled (not GPIO[32] function).
2. Set WDT output enable, presecaler and interrupt type into the WDT configuration register.
3. Get control base from the Base Address register.
4. Program Preload register's value according to unlocking sequence.
5. Set WDT timer mode into WDT Lock Register.
6. Enable WDT from WDT Lock register and program the functionality of the WDT LED.

To keep the timer from causing an interrupt or driving WDT\_TOUT#, the timer must be reloaded periodically. The frequency of reloads required is dependent on the value of the preload values. To reload the down-counter, the register unlocking sequence must be performed.

To disable WDT, set bit 1 of WDT Lock Register to 0.

# 5.4 WDT Utilities

Users can download the Intel® Watchdog Timer Control (Demo) Windows application from http://downloadfinder.intel.com/. Enter "6300ESB" in the search window and download the Embedded Drivers zip file. You will find the demo application in the Applications folder.

# 6 ePCI-X Bus Details

# 6.1 NuPRO-860 ePCI-X Bus

The NuPRO-860 provides both PCI-X and PCI buses. Bus-A supports 64-bit /66MHz PCI-X and bus-B supports 32-bit/33MHz PCI.

The ePCI-X Bus pin assignment is compatible with the PICMG 1.2 ePCI-X specification. In the following sections, we will describe the detailed signal definitions of the NuPRO-860 ePCI-X bus to assist in backplane selection and design.

Note: All ADLINK PCI-X backplanes are compatible with the NuPRO-860.

# 6.2 Global Signals

# Standby Supply (+3.3Vaux)

The NuPRO-860 onboard circuit generates 3.3Vaux power from the +5Vaux or +5V. Therefore, the NuPRO-860 does not require the backplane to provide +3.3Vaux.

# ATX Support

The ATX support signals include PWRGD, PSON#, PWRBT#, and +5Vaux. The NuPRO-860 design provides for ATX power control capability.

If the backplane does not provide +5Vaux, then PWRBT# and PSON# will not function under ATX power mode. In this situation, users must implement external wiring to switch on/off the power supply.

# JTAG

The NuPRO-860 does NOT implement JTAG signals.

# I²C Bus

The onboard SMBus is connected to the SER\_SCL and SER\_SDA pins.

# PME#

The NuPRO-860 implements the PME# signal and connects it to 6300ESB southbridge.

# 6.3 PCI-X Bus Signals

# Backplane Present

The a\_PRSNT# and b\_PRSNT# signals are connected to the Super I/O chip's GP25 and GP26 pins respectively. These signal are pulled to +3.3V via 4.7k resistors.

# VIO Electrical Keying

The NuPRO-860 monitors the VIO keying signals from the backplane.

# M66EN and PCIXCAP

Only Bus-A supports PCI-X at up to 66MHz. The M66EN and PCIXCAP signals of Bus-A can be used to program it to PCI mode.
