SOFTWARE COMMAND DEFINITIONS

Device operations are selected by writing specific ad-

dress and data sequences into the command register.

Writing incorrect address and data values or writing them

in the improper sequence will reset the device to the

read mode. Table 3 defines the valid register command

sequences. Note that the Erase Suspend (B0H) and

Erase Resume (30H) commands are valid only while the

Sector Erase operation is in progress. Either of the two

reset command sequences will reset the device (when

applicable).

All addresses are latched on the falling edge of WE# or

CE#, whichever happens later. All data are latched on

rising edge of WE# or CE#, whichever happens first.
