3 Functional Description

The following special function processor PMC pins, as defined by the draft Processor PMC Standard VITA-32-199x, are implemented on the PrPMC800/800ET as described in the following sections.

PRESENT# Signal

The PRESENT# signal on the PrPMC800/800ET module is grounded to indicate to the baseboard that the module is installed.

MONARCH# Signal

The MONARCH# input signal allows the baseboard to enable the monarch system controller features on the PrPMC800/800ET module. The PrPMC800/800ET will pull up the MONARCH# signal. If the baseboard grounds this pin, the PrPMC800/800ET module will operate as a monarch (master) and provide system initialization and PCI interrupt handling. If the baseboard leaves the MONARCH# pin floating, the PrPMC800/800ET will operate as a non-monarch (slave).

INTA#-INTD# Signals

The four PCI interrupt signals are routed to MPIC external interrupt inputs so that they can be monitored by the processor when the PrPMC800/800ET is operating in the monarch mode. The PrPMC800/800ET can generate an interrupt to the host board processor on any one PCI interrupt INTA#-INTD# by activating the PCI interrupt in the Harrier message passing unit. Refer to the interrupt section of the Harrier ASIC Programmer’s Reference Guide for interrupt assignments.

IDSELB, REQB#, and GNTB# Signals

The PrPMC800/800ET module uses the processor PMC second PCI agent signals IDSELB, REQB# and GNTB# for the IDSEL, REQ# and GNT# signals of the GD82559ER/82551IT Ethernet chip. IDSELB has a weak onboard pulldown and GNTB# has a weak onboard pullup so the module operates properly on baseboards that do not support a second PCI agent.

M66EN Signal

The no-Ethernet versions (-21x1, -22x1 and -62x1) of the PrPMC800/800ET module are designed to operate on a 33 MHz or 66 MHz PCI bus, depending on the state of the M66EN pin provided by the baseboard. The module will monitor the state of the M66EN pin and set the multiplier of the on board clock generator at power-up. If the M66EN pin is grounded, the clock ratio will be 3:1. If M66EN is high, the clock ratio will be set to 3:2.

RESETOUT_L Signal

The PrPMC RESETOUT_L output signal (P12-60) provides a means for the PrPMC800/800ET to reset the baseboard which in turn can reset the PrPMC800/800ET. The active low RESETOUT_L signal is generated whenever the PrPMC800/800ET power-up reset, Watchdog Timer 1 reset, debug reset, or a software generated module reset via the Harrier RESET OUT bit is active. The PMC PCI reset input signal will not generate RESETOUT_L. Refer to Figure 3-2for a diagram of the module reset logic.
