SYSTEM ERROR (SERR_L) REPORTING
PI7C8150A uses the P_SERR_L signal to report conditionally a number of system error
conditions in addition to the special case parity error conditions described in Section 6.2.3.
Whenever assertion of P_SERR_L is discussed in this document, it is assumed that the
following conditions apply:
In compliance with the PCI-to-PCI Bridge Architecture Specification, PI7C8150A asserts
P_SERR_L when it detects the secondary SERR_L input, S_SERR_L, asserted and the
SERR_L forward enable bit is set in the bridge control register. In addition, PI7C8150A
also sets the received system error bit in the secondary status register.
PI7C8150A also conditionally asserts P_SERR_L for any of the following reasons:

The parity error was detected on the target (secondary) bus but not on the initiator (primary) bus.

For PI7C8150A to assert P_SERR_L for any reason, the SERR_L enable bit must be
set in the command register.
Whenever PI7C8150A asserts P_SERR_L, PI7C8150A must also set the signaled
system error bit in the status register.
