Execute a clear status register command to clear the FMPRSF and
FMERSF bits to 0 (successfully completed state).
Check if the command was input correctly, and execute it again.
Execute a clear stats register command to clear the FMERSF bit
to 0 (successfully completed state).
Execute a block erase command.
Repeat steps (1), (2), and (3) at least three times until no block erase
error occurs.
Execute a clear stats register command to clear the FMPRSF bit
to 0 (successfully completed state).
Execute a block erase command again.
