Table 7-5 ASSERTION OF P_PERR#
Table 7-5 shows assertion of P_PERR#. This signal is set under the following conditions:
X = don’t care

PI7C7300D is either the target of a write transaction or the initiator of a read
transaction on the primary bus.
The parity-error-response bit must be set in the command register of primary
interface.
PI7C7300D detects a data parity error on the primary bus or detects S_PERR#
asserted during the completion phase of a downstream delayed write transaction on
the target (secondary) bus.
