Table 17-8 provides the same information as Table 17-7 but organized by function instead
of register field.
17.3 Data Direction Registers
These registers are used to program GPIO port signals as inputs or outputs. The data
direction bit for any line is ignored unless that line is configured for general purpose I/O in
