Unlike address parity errors, data parity errors are not considered as severe and
transactions are aborted. The following sections describe the sequence of events when
a data parity error is detected for the following transactions:
When the Intel
write transaction to one of the Intel
6300ESB ICH:
When the Intel
Hub Interface initiated read, it:
When the Intel
completion packet from a previous memory read request on PCI, the Intel
ICH:
Interface Target
When the Intel
request, it:
The parity errors response bit is set in the bridge control register (D28:3Eh,0)
Configuration Write Transactions
Read Transactions (inbound and outbound)
Posted Write Transaction
Does not write the data to the configuration register when parity error response is
enabled.
Sets the Detected Parity Error bit in the Primary status register (bit 15 of offset 06-
07h).
Generates NMI/SMI (depending on which is enabled) and sets the signaled system
error bit (bit 14) in the Primary status register, when the Parity Error Response
Enable bit in the command register (bit 6 of offset 04-05h) is set.
Sets the detected parity error bit in the secondary status register (bit 15 of offset
1E-1Fh).
Sets the Data parity detected bit in the secondary status register (bit 8 of offset 1E-
1Fh), when the secondary interface parity error response bit is set in the bridge
control register (bit ’0’ of offset 3E-3Fh).
Forces bad parity error with the data back to the initiator on the Hub Interface.
Sets the detected parity error bit in the primary status register (bit 15 of offset 06-
07h).
Sets the data parity detected bit in the primary status register (bit 8 of offset 06-
07h) and generates the NMI/SMI (depending on which is enabled), when the
primary interface parity error response bit is set in the command register (bit 6 of
offset 04-05h).
Forwards the bad parity with the data back to PCI.
Sets the data parity error detected bit in the status register (bit 15 of offset 06-
07h) of the target interface (PCI bridge primary).
