Section 20 Flash Memory
20.5
There are two kinds of flash memory program/erase protection: hardware and software protection.
20.5.1
Programming and erasing of flash memory is forcibly disabled or suspended by hardware
protection. In this state, the downloading of an on-chip program and initialization are possible.
However, an activated program for programming or erasure cannot program or erase locations in a
user MAT, and the error in programming/erasing is reported in the parameter FPFR.

Description
•
•
The program/erase interface registers
are initialized in the power-on reset
state (including a power-on reset by
the WDT) and standby mode and the
program/erase-protected state is
entered.
The reset state will not be entered by
a reset using the RES pin unless the
RES pin is held low until oscillation
has stabilized after power is initially
supplied. In the case of a reset during
operation, hold the RES pin low for the
RES pulse width that is specified in
the section on AC characteristics
section. If a reset is input during
programming or erasure, data values
in the flash memory are not
guaranteed. In this case, after holding
the RES pin low for 100 μs or longer,
execute erasure and then execute
program again.
