22.8
Protection
There are two kinds of flash memory program/erase protection, hardware protection and software
protection.
22.8.1
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 register 1
(FLMCR1), flash memory control register 2 (FLMCR2), erase block register 1 (EBR1), and erase
block register 2 (EBR2). The FLMCR1, FLMCR2, EBR1, and EBR2 settings are retained in the
error-protected state. (See table 22.8.)

Description
Program Erase
FWP pin
protection
• When a high level is input to the FWP pin, FLMCR1,
FLMCR2, EBR1, and EBR2 are initialized, and the
program/erase-protected state is entered.
Yes
Yes
Reset/standby
protection
• 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 specified in
the AC Characteristics section.
Yes
Yes
