19.19.2 Software Protection
Software protection can be implemented by setting the SWE bit in flash memory control register 1 (FLMCR1), erase
block registers 1 and 2 (EBR1, EBR2), and the RAMS bit in the RAM emulation register (RAMER). When software
protection is in effect, setting the P or E bit in FLMCR1 does not cause a transition to program mode or erase mode. (See
table 19-38.)

Emulation protection
Description
Clearing the SWE bit to 0 in FLMCR1 sets
the program/erase-protected state for all
blocks
(Execute in on-chip RAM or external
memory.)
Erase protection can be set for individual
blocks by settings in erase block registers
1 and 2 (EBR1, 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.
