AUTOMATIC SECTOR ERASE TIMING WAVEFORM

Sector indicated by A12 to A17 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)
