AUTOMATIC SECTOR ERASE TIMING WAVEFORM

Sector indicated by A13 to A18 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 and 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)
