Bits 31-16 are Status register and bits 15-0 are Command register. Reads to Status register behave normally. Bits in Status
register are cleared if the corresponding write data bits are '1' in a write operation.
Bits 15-0 are Command register. When 00H
is written to this register, the device is logically disconnected from the PCI bus
for all accesses except configuration accesses. The power up value of Command register is 00 H
.
Bit 31
