ATD Digital Input Enable on channel x (x = 7, 6, 5, 4, 3, 2, 1, 0) — 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.
