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.
