Figure 10. AUTOMATIC SECTOR ERASE TIMING WAVEFORM
Sector indicated by A12 to A17 are erased. External
erase verify is not required because data are verified
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)
