3 Functional Description

The PrPMC800/800ET module can function as a system controller (monarch mode) for the host board or as a slave processor (non-monarch) PMC, depending on the state of the MONARCH# signal from the PMC connector. When configured as the monarch, the PrPMC800/800ET’s PPCBug enumerates the PCI bus as well as monitor and service the four PCI interrupts.
