ATD Digital Input Enable on Channel Bits — This bit controls the digital input buffer from the analog input
pin (ANx) to PTADx data register.

0 Disable digital input buffer to PTADx
1 Enable digital input buffer to PTADx.
Note: Setting this bit will enable the corresponding digital input buffer continuously. If this bit is set while
simultaneously using it as an analog port, there is potentially increased power consumption because the
digital input buffer maybe in the linear region.
