Command Definitions
Writing specific address and data commands or sequences into the command
register initiates device operations. Table 31 and Table 32 define the valid register
command sequences. Writing incorrect address and data values or writing them
in the improper sequence may place the device in an unknown state. A reset com-
mand is then required to return the device to reading array data.
