(4) Erasure Execution
(4.1) Flash erase block select parameter (FEBS: general register R4 of CPU)
Initial value:
Initial value:
Bit
0
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 17.5.2, User Program Mode (Only in On-Chip
128-Kbyte and 64-Kbyte ROM Version).
This parameter specifies the erase-block number. Several block numbers cannot be specified.
