Analog-to-Digital Converter (ADC)
26.3.1 ADC Port I/O Pins
PTD6/ATD14/TACLK
share with the ADC channels.
The channel select bits define which ADC channel/port pin will be used as the input signal. The ADC
overrides the port I/O logic by forcing that pin as input to the ADC. The remaining ADC channels/port pins
are controlled by the port I/O logic and can be used as general-purpose I/O. Writes to the port register or
DDR will not have any affect on the port pin that is selected by the ADC. Read of a port pin which is in
use by the ADC will return a 0 if the corresponding DDR bit is at logic 0. If the DDR bit is at logic 1, the
value in the port data latch is read.

Do not use ADC channels ATD14 or ATD12 when using the
PTD6/ATD14/TACLK or PTD4/ATD12/TBCLK pins as the clock inputs for
the 16-bit Timers.
