(4) Erasure Execution
When flash memory is erased, the erase-block number on the user MAT must be passed to the
erasing program which is downloaded. This is set to the FEBS parameter (general register R4).
One block is specified from the block number 0 to 15.
For details on the erasing procedure, see section 22.5.2, User Program Mode.
