8.3.2.12
The data port associated with the ATD is general purpose I/O. The port pins are shared with the analog
A/D inputs AN7–AN0.
Read: Anytime
Write: Anytime, no effect
The A/D input channels may be used for general-purpose digital I/0.
8.3.2.13
The A/D conversion results are stored in 8 read-only result registers ATDDRHx/ATDDRLx. The result
data is formatted in the result registers based on two criteria. First there is left and right justification; this
selection is made using the DJM control bit in ATDCTL5. Second there is signed and unsigned data; this
selection is made using the DSGN control bit in ATDCTL5. Signed data is stored in 2’s complement
format and only exists in left justified format. Signed data selected for right justified format is ignored.
Read: Anytime
Write: Anytime, no effect in normal modes

A/D Channel x (ANx) Digital Input (x = 7, 6, 5, 4, 3, 2, 1, 0) — If the digital input buffer on the ANx pin is enabled
(IENx = 1) read returns the logic level on ANx pin (signal potentials not meeting V
an indeterminate value)).
If the digital input buffers are disabled (IENx = 0), read returns a “1”.
Reset sets all PORTAD bits to “1”.
