Timing Waveform
Automatic Programming
One byte of data is programmed. Verifying in fast algorithm and
additional programming by external control are not required because
these operations are executed automatically by an 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. Q0
to Q5(Q6 is for toggle bit; see toggle bit, DATA polling, timing
waveform) are in high impedance.
