Legend:
Note 1:

— = unimplemented, read as ‘0’. Shaded cells are not used by PORTA.
RA<5:4> and their associated latch and data direction bits are enabled as I/O pins based on oscillator
configuration; otherwise, they are read as ‘0’.
Implemented only when Master Clear functionality is disabled (MCLRE Configuration bit = 0).
RA1 and RA0 are only available as port pins when the USB module is disabled (UCON<3> = 0).
