8.2.1 Analog Input Pins
8-2
Each of the eight analog input pins (AN[7:0]) is connected to a multiplexer in the ADC.
The multiplexer selects an analog input for conversion to digital data.
Analog input pins can also be read as digital inputs, provided the applied voltage
meets V
into an 8-bit port (PORTADA), and referred to as PADA[7:0]. There is no data direction
register because port pins are input only.
