18.8.2
Software protection can be implemented by setting the SWE1 bit in FLMCR1, the SWE2 bit in
FLMCR2, erase block register 1 (EBR1), erase block register 2 (EBR2), and the RAMS bit in the
RAM control register (RAMCR). When software protection is in effect, setting the P1 or E1 bit in
flash memory control register 1 (FLMCR1), or the P2 or E2 bit in flash memory control register 2
(FLMCR2) does not cause a transition to program mode or erase mode. (See table 18.11.)

protection
Notes: 1. Two modes: program-verify and erase-verify.
2. When not erasing, clear all EBR1, EBR2 bits to H'00.
3. A RAM area overlapping flash memory can be written to.
4. All blocks are unerasable and block-by-block specification is not possible.
Software Protection
Description
Erase protection can be set for individual
blocks by settings in erase block register 1
(EBR1) *
However, programming protection is disabled.
Setting EBR1 and EBR2 to H'00 places all
blocks in the erase-protected state.
Setting the RAMS bit to 1 in the RAM
control register (RAMCR) places all blocks
in the program/erase-protected state.
