EXTENDED INSTRUCTION SET
All PIC18 instructions may take an optional label argument preceding the instruction mnemonic for use in
symbolic addressing. If a label is used, the instruction format then becomes: {label} instruction argument(s).

f [ 0, 1, 2 ]
FSR(f) + k FSR(f)

The 6-bit literal ‘k’ is added to the
contents of the FSR specified by ‘f’.

FSR2 + k FSR2,
(TOS) PC
None
The 6-bit literal ‘k’ is added to the
contents of FSR2. A RETURN is then
executed by loading the PC with the
TOS.
The instruction takes two cycles to
execute; a NOP is performed during
the second cycle.
This may be thought of as a special
case of the ADDFSR instruction,
where f = 3 (binary ‘11’); it operates
only on FSR2.
