WRITE ALL (WRAL): The write all (WRAL) instruction programs all memory locations with the data patterns specified in
the instruction. The DO pin outputs the ready/busy status of the part if CS is brought high after being kept low for a
minimum of 250ns (t
ERASE/WRITE DISABLE (EWDS): To protect against accidental data disturbance, the erase/write disable (EWDS)
instruction disables all programming modes, and should be executed after all programming operations. The operation of the
READ instruction is independent of both the EWEN and EWDS instructions, and can be executed at any time.
