Notes:
1. Register bits are read by READ FLAG STATUS REGISTER command. All bits are volatile.
2. These program/erase controller settings apply only to PROGRAM or ERASE command cy-
cles in progress, or to the specific WRITE command cycles in progress as shown here.
3. Status bits are reset automatically.
4. Error bits must be reset by CLEAR FLAG STATUS REGISTER command.
5. Typical errors include operation failures and protection errors caused by issuing a com-
mand before the error bit has been reset to 0.
