SYSTEM ERROR (SERR#) REPORTING
PI7C7300A uses the P_SERR# signal to report conditionally a number of system error
conditions in addition to the special case parity error conditions described in Section
7.2.3.
Whenever assertion of P_SERR# is discussed in this document, it is assumed that the
following conditions apply:
!
For PI7C7300A to assert P_SERR# for any reason, the SERR# enable bit must be
set in the command register.
!
Whenever PI7C7300A asserts P_SERR#, PI7C7300A must also set the signaled
system error bit in the status register.
In compliance with the PCI-to-PCI Bridge Architecture Specification, PI7C7300A
asserts P_SERR# when it detects the secondary SERR# input, S_SERR#, asserted and
the SERR# forward enable bit is set in the bridge control register. In addition,
PI7C7300A also sets the received system error bit in the secondary status register.
PI7C7300A also conditionally asserts P_SERR# for any of the following reasons:
!
Target abort detected during posted write transaction
!
Master abort detected during posted write transaction
!
Posted write data discarded after 2

!

section)

!
Delayed read data cannot be transferred from target after 2
