13.6 I/O Port Function Select
The value in the G1FE and G1FS registers decides which IC/OC pin to be an input or output pin.
In SR waveform generating mode, two channels, a set of even channel and odd channel, are used every
output waveform, however, the waveform is output from an even channel only. In this case, the correspond-
ing pin to the odd channel can be used as an I/O port.
