Section 29 Pin Function Controller (PFC)
29.3 Switching Pin Function of Port A
In port A, the analog input pins of A/D converter and the analog output pins of D/A converter are
multiplexed. Pin function is automatically changed by the settings of the A/D control/status
register in A/D converter and D/A control register in D/A converter. (See section 22, A/D
Converter (ADC), and section 23, D/A Converter (DAC).)
