and Erasing Precautions. The H8/3052BF requires at least 20 system clocks for a reset
during operation.
Description
When a low level is input to the FWE pin,
FLMCR1, FLMCR2, (except bit FLER) EBR1,
and EBR2 are initialized, and the program/
erase-protected state is entered. *
In a power-on reset (including a WDT power-on
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. *
When a microcomputer operation error (error
generation (FLER=1)) was detected while flash
memory was being programmed/erased, error
protection is enabled. At this time, the FLMCR1,
FLMCR2, EBR1, and EBR2 settings are held, but
programming/erasing is aborted at the time the
error was generated. Error protection is released
only by a reset via the RES pin or a WDT reset,
or in the hardware standby mode.
