AUTOMATIC PROGRAMMING TIMING
WAVEFORM
One byte data is programmed. Verify in fast algorithm and
additional programming by external control are not re-
quired because these operations are executed automati-
cally by internal control circuit. Programming completion
can be verified by DATA polling and toggle bit checking
