AUTOMATIC PROGRAMMING TIMING WAVEFORM

One byte data is programmed. Verification in fast

algorithm and additional programming by external control

are not required because these operations are executed

automatically by internal control circuit. Programming

completion can be verified by DATA polling and toggle bit

checking after automatic verify starts. Device outputs

DATA during programming and DATA after programming

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

timing waveform)
