AUTOMATIC SECTOR ERASE TIMING WAVEFORM
Sector indicated by A12 to A19 are erased. External
erase verify is not required because data are verified
automatically by internal control circuit. Erasure comple-
tion can be verified by Data# Polling or toggle bit check-
ing after automatic erase starts. Device outputs 0 dur-
ing erasure and 1 after erasure on Q7. (Q6 is for toggle
bit; see toggle bit, Data# Polling, timing waveform)
