3.7 PMC Site

The PMC site is connected to the PCI0 port of the MV64560. This bus supports 32- or
64-bit data widths and bus speeds up to 133 MHz. It is capable of using the PCI-X
protocol, but is backward compatible with standard PCI. The PMC bus speed can be
read from the EPLD
Only PMC cards that operate using 3.3 Volt signaling (VIO) are supported.
The PMC site supports Processor PMCs (as defined by VITA32-2002) operating in
non-Monarch mode only.
The four interrupts from the PMC site are wired together and routed to the interrupt
handler in the MV64560.
The MV64560 provides the PCI arbiter for the bus and supports two bus masters on
the PMC card.

CAUTION
Fitting a PMC designed to operate at 5 Volts VIO may cause damage to the IMP2B and/or PMC
CAUTION
The second bank of DDR2 memory occupies the PMC 'keep-out' area, which reduces the maximum
component height on a PMC from 10mm to 5mm in this area. When the second DDR2 bank is not
fitted, the full 10mm PMC component height is available.
