2.1 Configuration of the Power Supply
The power to the M32R/ECU can be supplied from two sources, AVCC and VCCE independently of
each other. With default settings, the power to the M32R/ECU is fed through the VCCE power
supply connector to all of its internal circuits.
Note: H1, TX1 and TX18 are not mounted but they only have patterns available.
