Data# Polling and Toggle Bits
鈥?Provides a software method of detecting
program or erase cycle completion
s
Ready/Busy pin (RY/BY#)
鈥?Provides a hardware method for detecting
program or erase cycle completion
s
Erase Suspend/Erase Resume
鈥?Suspends an erase operation to read data from,
or program data to, a sector that is not being
erased, then resumes the erase operation
s
Hardware RESET# pin
鈥?Hardware method of resetting the device to
reading array data
