MOVF
Move f
Syntax:
[
label ]
MOVF f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f)
→ (destination)
Status Affected:
Z
Description:
The contents of register f are
moved to a destination dependant
upon the status of d. If d = 0, des-
tination is W register. If d = 1, the
destination is file register f itself.
d = 1 is useful to test a file register,
since status flag Z is affected.
MOVLW
Move Literal to W
Syntax:
[
label ]
MOVLW k
Operands:
0
≤ k ≤ 255
Operation:
k
→ (W)
Status Affected:
None
Description:
The eight-bit literal ’k’ is loaded
into W register. The don’t cares
will assemble as 0’s.
MOVWF
Move W to f
Syntax:
[
label ]
MOVWF
f
Operands:
0
≤ f ≤ 127
Operation:
(W)
→ (f)
Status Affected:
None
Description:
Move data from W register to
register 'f'.
NOP
No Operation
Syntax:
[
label ]
NOP
Operands:
None
Operation:
No operation
Status Affected:
None
Description:
No operation.
RETFIE
Return from Interrupt
Syntax:
[
label ]
RETFIE
Operands:
None
Operation:
TOS
→ PC,
1
→ GIE
Status Affected:
None
RETLW
Return with Literal in W
Syntax:
[
label ]
RETLW k
Operands:
0
≤ k ≤ 255
Operation:
k
→ (W);
TOS
→ PC
Status Affected:
None
Description:
The W register is loaded with the
eight-bit literal 'k'. The program
counter is loaded from the top of
the stack (the return address).
This is a two-cycle instruction.
RETURN
Return from Subroutine
Syntax:
[
label ]
RETURN
Operands:
None
Operation:
TOS
→ PC
Status Affected:
None
Description:
Return from subroutine. The stack
is POPed and the top of the stack
(TOS) is loaded into the program
counter. This is a two-cycle
instruction.
