AUTOMATIC PROGRAMMING TIMING

WAVEFORM

One byte data is programmed. Verify in fast algorithm

and additional verification by external control are not re-

quired because these operations are executed automati-

cally by internal control circuit. Programming comple-

tion can be verified by DATA polling and toggle bit checking

after automatic programming starts. Device outputs

DATA during programming and DATA after programming

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

timing waveform)
