All data in chip are erased. External erase verification is
not required because data is verified automatically by
internal control circuit. Erasure completion can be veri-
fied by Data# Polling and toggle bit checking after auto-
matic 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)
