17.10
There are three kinds of flash memory program/erase protection: hardware protection, software
protection, and error protection.
17.10.1 Hardware Protection
Hardware protection refers to a state in which programming/erasing of flash memory is forcibly
disabled or aborted. Hardware protection is reset by settings in flash memory control registers 1
and 2 (FLMCR1, FLMCR2) and erase block registers 1 and 2 (EBR1, EBR2). (See table 17.16.)

Flash Memory Protection
Description
When a low level is input to the FWE pin,
FLMCR1, FLMCR2 (excluding the FLER
bit), EBR1, and EBR2 are initialized, and
the program/erase-protected state is
entered.
In a reset (including a WDT overflow
reset) and in standby mode, FLMCR1,
FLMCR2, EBR1, and EBR2 are initialized,
and the program/erase-protected state is
entered.
In a reset via the RES pin, the reset state
is not entered unless the RES pin is held
low until oscillation stabilizes after
powering on. In the case of a reset during
operation, hold the RES pin low for the
RES pulse width (t
