Bit
Function
Type
Description
Controls PI7C7300A’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
Reserved. Returns 0 when read. Reset to 0
