NOTE:
4. When either the FMR06 or FMR07 bit is 1 (terminated by error), the program command, block erase command, lock bit program
command, and read lock bit status command cannot be accepted. Execute the clear status register command before executing
these commands.

(1) Execute the clear status register command to set bits FMR06 and FMR07 to 0
(2) Check if the command is written correctly and execute the correct command.
(1) Execute the clear status register command to set the erase status flag to 0
(2) Execute the read lock bit status command. Set the FMR02 bit in the FMR0
(3) Execute the block erase command again.
NOTE:
[When a program operation is executed]
(1) Execute the clear status register command to set the program status flag to 0.
(2) Execute the read lock bit status command. Set the FMR02 bit to 1 if the lock bit
NOTE:
[When a lock bit program operation is executed]
(1) Execute the clear status register command to set the program status flag to 0.
(2) Set the FMR02 bit to 1.
(3) Execute the block erase command to erase the block where the error has
