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
