2.3 MOD Select Circuit
This circuit is used to set operation modes of the M32R/ECU. The MOD0 power supply is
configured in such a way that MOD0 is switched from the EXTMOD0 signal of extension connector
(CON2) by using a jumper (J8).
The MOD1 power supply defaults to 0 V. The MOD2 power supply is fixed to 0 V.
