22.8
There are three kinds of flash memory program/erase protection: hardware protection, software
protection, and error protection.
22.8.1
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 22.8.)
Table 22.8 Hardware Protection
22.8.2
Software protection can be implemented by setting the SWE bit in FLMCR1 and erase block
registers 1 and 2 (EBR1, EBR2). 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 22.9.)

Description
In a reset (including a WDT overflow reset)
and in hardware standby mode, software
standby mode, subactive mode, subsleep
mode, and watch 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
specified in the AC Characteristics section.
