Posted Write
Parity Error
R/W
Controls PI7C7300D’s ability to assert P_SERR# when it is unable to
transfer any read data from the target after 2
24 attempts.
0: P_SERR# is asserted if this event occurs and the SERR# enable bit
in the command register is set.
1: P_SERR# is not assert if this event occurs.
Reset to 0

Posted Write
Non-Delivery
R/W
Controls PI7C7300D’s ability to assert P_SERR# when it is unable to
transfer delayed write data after 2
24 attempts.
0: P_SERR# is asserted if this event occurs and the SERR# enable bit
in the command register is set
1: P_SERR# is not asserted if this event occurs
Reset to 0

Target Abort
During Posted
Write
R/W
Controls PI7C7300D’s ability to assert P_SERR# when it receives a
target abort when attempting to deliver posted write data.
0: P_SERR# is asserted if this event occurs and the SERR# enable bit
in the command register is set
1: P_SERR# is not asserted if this event occurs
Reset to 0
