Section 17 ROM
17.10.2 Software Protection
Software protection can be implemented by setting the SWE bit in FLMCR1, erase block registers
1 and 2 (EBR1, EBR2), and the RAMS bit in RAMER. When software protection is in effect,
setting the P or E bit in flash memory control register 1 (FLMCR1) does not cause a transition to
program mode or erase mode. (See table 17.17.)

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).
However, write 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
emulation register (RAMER) places all
blocks in the program/erase-protected
state.
