23.2.2
The ADRESH:ADRESL register pair is where the 12-bit
A/D result and extended sign bits (ADSGN) are loaded
at the completion of a conversion. This register pair is
16 bits wide. The A/D module gives the flexibility of left
or right justifying the 12-bit result in the 16-bit result
register. The A/D Format Select bit (ADFM) controls
this justification.

(ADSGN). The extended sign bits allow for easier
16-bit math to be performed on the result.
When the A/D Converter is disabled, these 8-bit
registers can be used as two, general purpose registers.
