Legend:
x
= unknown,
u
= unchanged,
q
= value depends on condition, - = unimplemented, read as ‘0’, r = reserved.
Shaded locations are unimplemented, read as ‘0’.
These registers can be addressed from any bank.
The upper byte of the program counter is not directly accessible. PCLATH is a holding register for the PC<12:8>, whose contents are
transferred to the upper byte of the program counter.
Pin 5 is an input only; the state of the TRISA5 bit has no effect and will always read ‘1’.
