2:
Connect the user reset circuit to the RESET pin with the shortest possible wiring.
In the normal microcomputer mode, disconnect a wiring of a serial rewrite circuit,
which is for the flash memory version, from the MCU by a jumper switch.
Connect the CNVss pin to the Vss pin with the shortest possible wiring.
In the normal microcomputer mode, disconnect a wiring of a serial rewrite circuit,
which is for the flash memory version, from the MCU by a jumper switch.
