AUTOMATIC PROGRAMMING TIMING

WAVEFORM

One byte data is programmed. Verify in fast algorithm

and additional programming by external control are not

required because these operations are executed auto-

matically by internal control circuit. Programming

completion can be verified by DATA polling and toggle

bit checking after automatic verification starts. Device

outputs DATA during programming and DATA after pro-

gramming on Q7.(Q6 is for toggle bit; see toggle bit,

DATA polling, timing waveform)
