Legend:
x = unknown, u = unchanged, q = value depends on condition, - = unimplemented, read as ‘0’, r = reserved.
Shaded locations are unimplemented, read as ‘0’.
Note 1:
The upper byte of the program counter is not directly accessible. PCLATH is a holding register for PC<12:8>, whose
contents are transferred to the upper byte of the program counter.
2:
These registers can be addressed from any bank.
3:
RA5 is an input only; the state of the TRISA5 bit has no effect and will always read ‘1’.
4:
PIC16F88 device only.
