REJ09B0300-0300
The output type on port G is NMOS push-pull output. Port G can be 5-V tolerant.
When port G is used as an output pin, connect a pull-up resistor to the pin for raise an output high-
level voltage.

8.14 Ports C, D
Port C and port D are two sets of 8-bit I/O ports. The pin functions are the same in all operating
modes.
