Boot mode can be released by driving the reset pin low, waiting at least ten system clock
cycles, then releasing the application of 12 V to the MD
The settings of external pins must not change during operation in boot mode.
During boot mode, if input of 12 V to the MD
pin, the boot mode state is maintained within the chip and boot mode continues (but do not
stop applying 12 V to the FV
If a watchdog timer reset occurs during boot mode, this does not release the internal mode
state, but the internal boot program is restarted.
Therefore, to change from boot mode to another mode, the boot-mode state within the chip
must be released by a reset input at the RES pin before the mode transition can take place.
while the input to the RES pin is low), the resultant switch in the microcontroller’s operating
mode will affect the bus control output signals (AS, RD, and WR) and the status of ports that
can be used for address output
Therefore, either set these pins so that they do not output signals during the reset, or make sure
that their output signals do not collide with other signals outside the microcontroller.

the reset. In all other modes, these ports are in the high-impedance state. The bus
control output signals are high if the mode pins are set for mode 1 or 2 during the reset.
In mode 3, they are at high impedance.
