Flash memory can be protected from programming and erasing by software or hardware methods.
These two protection modes are described below.
Software Protection: Prevents transitions to program mode and erase mode even if the P or E bit
is set in the flash memory control register (FLMCR). Details are as follows.

Notes: 1. Three modes: program-verify, erase-verify, and prewrite-verify.
2. Except in RAM areas overlapped onto flash memory.
3. All blocks are erase-disabled. It is not possible to specify individual blocks.
Protect Modes
Description
Individual blocks can be erase and
program-protected by the erase block
registers (EBR1 and EBR2). If EBR1 and
EBR2 are both set to H'00, all blocks are
erase- and program-protected.
When the RAMS bit is set in the RAM
control register (RAMCR), all blocks are
protected from both programming and
erasing.
