AUTOMATIC SECTOR ERASE TIMING WAVEFORM
Block data indicated by A16 to A19 are erased. External
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
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)
