Software protection can be implemented by setting the SWE1 bit in FLMCR1, erase block register
1 (EBR1), erase block register 2 (EBR2), and the RAMS bit in the RAM emulation register
(RAMER). When software protection is in effect, setting the P1 or E1 bit in flash memory control
register 1 (FLMCR1), does not cause a transition to program mode or erase mode. (See table
19.9.)

Software Protection
Description
Setting bit SWE1 in FLMCR1 to 0 will
place area H'000000 to H'03FFFFF in the
program/erase-protected state. (Execute
the program in the on-chip RAM, external
memory)
Erase protection can be set for individual
blocks by settings in erase block register 1
(EBR1) and erase block register 2
(EBR2).
Setting EBR1 and EBR2 to H'00 places all
blocks in the erase-protected state.
Setting the RAMS bit to 1 in the RAM
emulation register (RAMER) places all
blocks in the program/erase-protected
state.
