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).
— = unimplemented, read as ‘0’. Shaded cells are not used by PORTA.
These bits are enabled depending on the oscillator mode selected. When not enabled as PORTA pins, they are
disabled and read as ‘x’.
