4.3.2.14
The data port associated with the ATD is input-only. The port pins are shared with the analog A/D inputs
AN[15:8].
Read: Anytime
Write: Anytime, no effect
The A/D input channels may be used for general-purpose digital input.

A/D Channel x (ANx) Digital Input Bits— If the digital input buffer on the ANx pin is enabled (IENx = 1) or
channel x is enabled as external trigger (ETRIGE = 1, ETRIGCH[3-0] = x, ETRIGSEL = 0) read returns the
logic level on ANx pin (signal potentials not meeting V
If the digital input buffers are disabled (IENx = 0) and channel x is not enabled as external trigger, read returns
a “1”.
Reset sets all PORTAD0 bits to “1”.
