Target Abort
During Posted
Write
RW
Controls bridge’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
4
Master Abort
On Posted
Write
RW
Controls bridge’s ability to assert P_SERR# when it receives a master 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
5
Delayed Write
Non-Delivery
RW
Controls bridge’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
6
Delayed Read –
No Data From
Target
RW
Controls bridge’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 asserted if this event occurs
Reset to 0
