AUTOMATIC SECTOR ERASE TIMING WAVEFORM
Sector data indicated by A13 to A17 are erased. Exter-
nal erase verification is not required because data are
erased automatically by internal control circuit. Erasure
completion can be verified by DATA polling and toggle bit
checking after automatic erase starts. Device outputs 0
during erasure and 1 after erasure on Q7.(Q6 is for toggle
bit; see toggle bit, DATA polling, timing waveform)
