AUTOMATIC SECTOR ERASE TIMING WAVEFORM
Sector data indicated by A12 to A17 are erased. Exter-
nal erase verify is not required because data are erased
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)
