⎯ There are many commands other than programming/erasing. Examples are sum check,
programming/erasing command. The erasure must be used when the specified block is
programmed without a reset start after programming is executed in boot mode. When
programming can be executed by only one operation, all blocks are erased before the state
for waiting programming/erasing/other command is entered. The erasing operation is not
required.
