Command
Read/Write

The Command register provides coarse control over a device’s ability to
generate and respond to PCI cycles. When a zero is written to this
register, the LSI53C810A is logically disconnected from the PCI bus for
all accesses except configuration accesses.

In the LSI53C810A, bits 3, 5, 7, and 9 are not implemented. Bits 10
through 15 are reserved.
