This bit disables the device from asserting INTx#. logic 1 = dis-
0b
able assertion of INTx# and logic 0 = enables assertion of INTx#
SERR# driver enable. logic 1=enable driver and 0=disable driver
0b
Parity error enable. logic 1=respond to parity error and 0=ignore
0b
Command controls a device’s response to mem space accesses:
0b
0=disable mem space accesses, 1=enable mem space accesses
Device’s response to I/O space accesses is disabled.
0b
(0 = disable I/O space accesses)
