Device Command Bus Cycles
Device operations are initiated by writing specific device commands to the Command
User Interface (CUI). 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.
