Status Affected: None
The contents of register ’f’ are comple-
mented. If ’d’ is 0, the result is stored
in W. If ’d’ is 1, the result is stored
back in register ’f’.
GOTOis an unconditional branch. The
Description:
eleven bit immediate value is loaded
into PC bits <10:0>. The upper bits of
PC are loaded from PCLATH<4:3>.
GOTOis a two-cycle instruction.

Decrement register ’f’. If ’d’ is 0, the
result is stored in the W register. If ’d’
is 1, the result is stored back in
register ’f’.
The contents of register ’f’ are incre-
mented. If ’d’ is 0, the result is placed
in the W register. If ’d’ is 1, the result is
placed back in register ’f’.

If the result is 1, the next instruction is
executed. If the result is 0, then a NOP
is executed instead making it a 2 TCY
instruction.
