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)
