I²C clock input/output pins.
These functions have a bus driving function.
SCL0's output format is an NMOS open drain.
A/D converter AN15 to AN0 Input Analog 15 to 0: Analog input pins.
ADTRG
Input
A/D conversion external trigger input: Pin for input of
an external trigger to start A/D conversion.
D/A converter DA3 to DA0 Output Analog output: Analog output pins for D/A converter.
