Operation
This section describes the requirements and use of the device bus operations,
which are initiated through the internal command register. The command register
itself does not occupy any addressable memory location. The register is a latch
used to store the commands, along with the address and data information
needed to execute the command. The contents of the register serve as inputs to
the internal state machine. The state machine outputs dictate the function of the
device.

these operations in further detail.
