General-purpose I/O port
This function is valid when the UART1 clock output is
disabled.
UART1 clock I/O pin
During UART1 input operations, UART1 inputs may be
used at any time.
It is necessary to stop port output when UART1 inputs,
except using port output deliberately.
General-purpose I/O port
This function is valid when the PPG timer 0 waveform
output is disabled.
PPG timer 0 output pin
This function is valid when the PPG timer 0 waveform
output is enabled.
General-purpose I/O port
This function is always valid.
A/D converter trigger input pin
During A/D converter input operations, A/D converter
inputs may be used at any time.
It is necessary to stop port output when A/D converter
inputs, except using port output deliberately.
