AUTOMATIC CHIP ERASE TIMING WAVEFORM

All data in chip are erased. External erase verification is

not required because data is erased 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 0n Q7.(Q6 is for toggle bit; see toggle bit,

DATA polling, timing waveform)
