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.

Standard serial I/O mode 1
Figure 110 shows the handling example of control pins on the user
system board when the standard serial I/O mode 1 is used.
Refer to the serial programmer manual of your programmer to
handle pins controlled by the programmer.
