11.3.2.2 Checking of Protective Signals
The bus initiator checks the following signals:
- Parity of read data
- Bus error response from data bus
The bus matrix checks the parity of addresses mapped to the I/O bus bridge to ensure that the initiator select signals generated from this address are correct. Address parity on high-speed bus addresses is not checked by the bus matrix but is left to the high-speed bus targets.
The target checks the following signals:
- Parity on address
- Parity on write data
- Consistency of bus control signals
