19.6.3 Notes on Analog Pins
The AN8 to AN15 pins also function as port G pins. Therefore, switching input/output of port G
or changing the output value during A/D conversion may affect the conversion accuracy. Evaluate
the accuracy of A/D conversion sufficiently, when port G is used as a general I/O port.
