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 syntax then becomes: {label} instruction argument(s).

Add Literal to FSR2 and Return
ADDULNK k
0  k  63
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.
