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 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.

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 the  
“Sector Group Protection and Unprotection” section.  
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 will be  
protected or unprotected as determined by the method described in “Sector Group Protection and Unprotection”.  
All sectors are unprotected when shipped from the factory (The SecSi 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 2).
