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
programming on Q7.(Q6 is for toggle bit; see toggle bit,
DATA polling, timing waveform).
