The contents of register ‘f’ are
decremented. 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 T
CY
instruction.

The contents of register ‘f’ are
incremented. 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’, a
NOP
is executed
instead, making it a 2 T
CY
instruction.

None
GOTO
is an unconditional branch.
The eleven-bit immediate value is
loaded into PC bits<10:0>. The
upper bits of PC are loaded from
PCLATH<4:3>.
GOTO
is a
two-cycle instruction.

The contents of the W register are
ORed with the eight-bit literal ‘k’.
The result is placed in the W
register.

The contents of register ‘f’ are
incremented. If ‘d’ is ‘0’, the result
is placed in the W register. If ‘d’ is
‘1’, the result is placed back in
register ‘f’.

Inclusive OR the W register with
register ‘f’. If ‘d’ is ‘0’, the result is
placed in the W register. If ‘d’ is
‘1’, the result is placed back in
register ‘f’.
