Notes:
1. Addresses are Amax:A0 in word mode; Amax:A-1 in byte mode. Sector addresses are Amax:A15 in both modes.
2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the

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. Table 1 lists the device bus operations, the inputs and control levels they
require, and the resulting output. The following subsections describe each of
these operations in further detail.
