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. Table 7.1 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.
Legend
L = Logic Low = VIL, H = Logic High = VIH, X = Don’t Care, VID = 11.5–12.5 V, VHH = 11.5–12.5 V, SA = Sector Address,
AIN = Address In, DIN = Data In, DOUT = Data Out
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 Sector Group Protection
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
sector devices). If WP# = VIH, the first or last sector, or the two outer boot sectors are protected or unprotected as determined by the
method described in Sector Group Protection and Unprotection on page 41. All sectors are unprotected when shipped from the factory
(The Secured Silicon Sector may be factory protected depending on version ordered.)
4. DIN or DOUT as required by command sequence, data polling, or sector protect algorithm (see Figure 10.3 on page 64).
