Device Bus Operations
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.
control levels they require, and the resulting output. The following subsections describe each of these
operations in further detail.

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
3. If WP# = VIL, the first or last sector remains protected (for uniform sector devices), and the two outer boot sectors are protected (for boot
