Table 29: PORTA register bit definition
PORTA Configuration
The ADIR and AMODE bits together provide independent configuration of each pin.
Each column in this table denotes one of the possible configurations for each bit. If
there is no entry in one of the columns (for example,
cannot be used in that configuration.

PORTA data register
Used when a PORTA bit is configured to operate in GPIO
mode.
Each bit in the ADATA field corresponds to one of the
PORTA bits; D07 controls PORTA7, D06 controls
PORTA6, and so on.
