O = Output, I = Input, ANA = Analog Signal, DIG = Digital Output, ST = Schmitt Trigger Buffer Input,
TTL = TTL Buffer Input, x = Don’t care (TRIS bit does not affect port direction or is overridden for this option).
These bits are enabled depending on the oscillator mode selected. When not enabled as PORTA pins,
they are disabled and read as ‘x’.
