Device Commands

Device operations are initiated by writing specific device commands to the Command User

Interface (CUI). See Table 20, “Command Bus Cycles” on page 50. Several commands are used to

modify array data including Word Program and Block Erase commands. Writing either command

to the CUI initiates a sequence of internally-timed functions that culminate in the completion of the

requested task. However, the operation can be aborted by either asserting RST# or by issuing an

appropriate suspend command.
