D = WD
A
= 0 loads low byte
of Data Register.
A

of Data Register.
Other Addresses = X
NOTE:
If CSR.4, 5 is set, as it is command sequence error,
should be cleared before further attempts are initiated.
CSR Full Status Check can be done after each 2-Byte Write,
or after a sequence of 2-Byte Writes.
Write FFH after the last operation to reset device to read
array mode.
See Command Bus Cycle notes for description of codes.
