The system can determine the status of the erase operation by reading the Status Register or using Data
Polling. Refer to
on page 40
Once the sector erase operation has begun, the Status Register Read and Erase Suspend commands are
valid. All other commands are ignored. However, note that a hardware reset immediately terminates the
erase operation and returns to read mode after t
erase command sequence must be reinitiated once the device has reset operation to ensure data integrity.
