Hello,
After going through the PCI-X Addedum Rev. 1.0, I have
some doubts. I will be thankful if anyone clarifies them.
This is regarding the SERR# assertion during Data Parity
Error.[Ref. 5.4.1 pg.no.121-122]
There it is mentioned that, if the Data Parity Error Recovery
Bit is cleared [i.e. system can not recover from data parity error], SERR# is to
be asserted.
The doubt is : for assertion of SERR# [the clock on which
SERR# is asserted], whether it should follow PCI2.2 std. or PCIX
std.?
whether the assertion of SERR# is to be reported in status register? If yes,
which bit?[SERR# detected or PERR# detected]
whether PERR# also is to be asserted?
Madhura.
