3 Functional Description

Harrier I2C port 0 is also routed to pins on the P14 PMC user I/O connector. The connection to the PMC connector provides a means to interface to an optional configuration SROM on the baseboard. This allows the PrPMC800/800ET to determine hardware configuration information from the baseboard. Refer to the Harrier ASIC Programmer’s Reference Guide for SROM device address assignments.

10BaseT/100BaseTX Ethernet Channel

The PrPMC800/800ET module uses an Intel GD82559ER/82551IT Ethernet controller to implement a 10BaseT/100BaseTX Ethernet channel. The GD82559ER/82551IT is a lower power, lower cost version of the GD82559 without the wake-on-LAN features. The GD82559ER/82551IT consists of both the Media Access Controller (MAC) and the physical layer (PHY) in a single integrated package. A Pulse H0013 low profile transformer is used to supply the external magnetics. The module will support a front panel Ethernet connection via a low profile PC card style connector mounted at the front of the module (on models -12x1 and - 52x1). Optional rear I/O Ethernet is provided by routing the Ethernet transmit and receive signal pairs to P14 connector (on models -11x9, -12x9, and -52x9).

The 82559ER/82551IT interfaces to an AT93C46 serial EEPROM device that provides power- up configuration information for the 82559ER/82551IT. This is a 1Kb device organized as 64 16- bit words. Refer to the corresponding table in the VPD appendix of the PrPMC800/800ET Processor PMC Module Programmer’s Reference Guide, for the contents of this device.

Miscellaneous Control and Status

The Harrier ASIC contains a Miscellaneous Control and Status register that provides the PrPMC800/800ET module with the module fail LED control, PrPMC EREADY# pin status, PrPMC MONARCH# pin status, module reset control, and processor timebase enable control. Refer to the Harrier ASIC Programmer’s Reference Guide for additional details.

Timers

Timers on the PrPMC800/800ET board are provided by the Harrier ASIC. Refer to the Harrier ASIC documents for programming details on these timers.

32-Bit Timers

Four 32-bit timers are provided by Harrier (MPIC) that may be used for system timing or to generate periodic interrupts. Each timer is driven by a divide-by-eight prescaler which is synchronized to the Power PC processor clock. For a 100 MHz processor bus, the timer frequency would be 12.5 MHz.
