SYSTEM ERROR (SERR#) REPORTING
PI7C8150 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 7.2.3.
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, PI7C8150 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, PI7C8150 also
sets the received system error bit in the secondary status register.
PI7C8150 also conditionally asserts P_SERR_L for any of the following reasons:

The device-specific P_SERR_L status register reports the reason for the assertion of
P_SERR_L. Most of these events have additional device-specific disable bits in the
P_SERR_L event disable register that make it possible to mask out P_SERR_L assertion

For PI7C8150 to assert P_SERR_L for any reason, the SERR_L enable bit must be set
in the command register.
Whenever PI7C8150 asserts P_SERR_L, PI7C8150 must also set the signaled system
error bit in the status register.
