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 the PC<12:8>, whose
contents are transferred to the upper byte of the program counter during branches (CALL or GOTO).
2:
Other (non power-up) RESETS include external RESET through MCLR and Watchdog Timer Reset.
3:
Bits PSPIE and PSPIF are reserved on the 28-pin devices; always maintain these bits clear.
4:
These registers can be addressed from any bank.
5:
PORTD, PORTE, TRISD, and TRISE are not physically implemented on the 28-pin devices, read as ‘0’.
6:
This bit always reads as a ‘1’.
