Table 6-4. Setting Secondary Interface Master Data Parity Error Detected Bit
Table 6-5. Assertion of P_PERR#
Table 6–4 shows setting the data parity detected bit in the status register of secondary
interface. This bit is set under the following conditions:
!

!
Table 6–5 shows assertion of P_PERR_L. This signal is set under the following conditions:

The PI7C8150 must be a master on the secondary bus.
The parity error response bit must be set in the bridge control register of secondary
interface.
The S_PERR_L signal is detected asserted or a parity error is detected on the
secondary bus.
PI7C8150 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.
PI7C8150 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.
