PCI Interface

The PrPMC800/800ET module contains four EIA-E700 AAAB connectors that provide a 32/64- bit PCI interface to an IEEE P1386.1 PMC compliant baseboard. Connectors P11-P13 provide the 32/64-bit 66 MHz capable PCI interface while P14 provides an I/O path from the module to the baseboard. Signals routed to P14 include the I2C bus, the RS-232 debug port, the processor JTAG/COP and the Xport 1.

PCI bus pullup resistors required by the PCI Revision 2.1 Specification (for motherboards), including 64-bit expansion signals, must be supplied by the baseboard. This is required if the PrPMC800/800ET is operating as a monarch or non-monarch module.
