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 excuted auto-
matically 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. Q0 to Q5 (Q6 is for toggle bit; see toggle bit, DATA
polling, timing waveform) are in high impedance.
