13.4.2.2
The input channel pins can be multiplexed between analog and digital data. As analog inputs, they are
multiplexed and sampled as analog channels to the A/D converter. The analog/digital multiplex operation
is performed in the input pads. The input pad is always connected to the analog input channels of the
ADC12B16C. The input pad signal is buffered to the digital port registers. This buffer can be turned on or
off with the ATDDIEN register. This is important so that the buffer does not draw excess current when
analog potentials are presented at its input.
