AUTOMATIC PROGRAMMING TIMING
WAVEFORM
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)
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
