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 check-
ing 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)
