3.10.2 Processor Interface Lines
3.10.3 Processor Interface I/O Lines Description
The processor interface is synchronized to the external processor clock. This clock operates at a different
frequency than the switch fabric clock.

MP_DATA_PRTY
BiDI
1 bit
Data Byte ODD Parity Bit - Hi-Z when no access being processed. The converter
checks during write operation and generates during read operation. Parity checker
can be disabled.

1 bit
Read/Write line
Low
Read Operation Write Operation
High
MP_PRDY
Out
Ready signal - Asserted High when data is valid on the bus (for read) or when data
is written into converter (for write). Driven by converter. Hi-Z when converter not
selected
