Move f to W
MOVFW f
0 ≤ f ≤ FFh
[W] ← [f]
None
Move data from [f] to the W
register.
1
Before instruction:
After instruction:
Move W to f
MOVWF f
0 ≤ f ≤ FFh
[f] ← [W]
None
Move data from the W register to
[f].

Before instruction:
After instruction:
Return from Interrupt
RETFIE
[Top Stack] => PC
Pop Stack
1 => GIE
None
The program counter is loaded
from the top stack, then pop
stack. Setting the GIE bit enables
interrupts.

Description
Move literal to W
MOVLW k
0 ≤ k ≤ FFh
[W] ← k
None
Move the eight-bit literal "k" to the
content of the W register.
1
Before instruction:
After instruction:
No Operation
NOP
No Operation
None
No operation. NOP is used for
one instruction cycle delay.
1
Return and move literal to W
RETLW k
0 ≤ k ≤ FFh
[W] ← k
[Top Stack] => PC
Pop Stack
None
Move the eight-bit literal "k" to the
content of the W register. The
program counter is loaded from
the top stack, then pop stack.
