!
PI7C8150B detects a data parity error on the primary bus or detects S_PERR_L
asserted during the completion phase of a downstream delayed write transaction on the
target (secondary) bus.

The parity error was detected on the target (secondary) bus but not on the initiator (primary) bus.
Table 6-6 shows assertion of S_PERR_L that is set under the following conditions:
!
PI7C8150B is either the target of a write transaction or the initiator of a read
transaction on the secondary bus.
!
The parity error response bit must be set in the bridge control register of secondary
interface.
!
PI7C8150B detects a data parity error on the secondary bus or detects P_PERR_L
asserted during the completion phase of an upstream delayed write transaction on the
target (primary) bus.
