IORLW
Inclusive OR literal with W
Syntax:
[ label ] IORLW k
Operands:
0 ≤ k ≤ 255
Operation:
(W) .OR. (k) → (W)
Status Affected: Z
Encoding:
1101 kkkk kkkk
Description:
The contents of the W register are
OR’ed with the eight-bit literal ‘k’.
The result is placed in the W
register.
Words:

Example:
IORLW 0x35
Before Instruction
W = 0x9A
After Instruction
W = 0xBF
Z =0
IORWF
Inclusive OR W with f
Syntax:
[ label ] IORWF f, d
Operands:
0 ≤ f ≤ 31
d ∈ [0,1]
Operation:
(W).OR. (f) → (dest)
Status Affected: Z
Encoding:
0001 00df ffff
Description:
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’.

Example:
IORWF

MOVF
Move f
Syntax:
[ label ] MOVF f, d
Operands:
0 ≤ f ≤ 31
d ∈ [0,1]
Operation:
(f) → (dest)
Status Affected: Z
Encoding:
0010 00df ffff
Description:
The contents of register ‘f’ is
moved to destination ‘d’. If ‘d’ is ‘0’,
destination is the W register. If ‘d’
is ‘1’, the destination is file
register ‘f’. ‘d’ is ‘1’ is useful to test
a file register since Status flag Z is
affected.

Example:
MOVF FSR, 0
After Instruction
W = value in FSR register
MOVLW
Move Literal to W
Syntax:
[ label ] MOVLW k
Operands:
0 ≤ k ≤ 255
Operation:
k → (W)
Status Affected: None
Encoding:
Description:
Words:
Cycles:
1100 kkkk kkkk
The eight-bit literal ‘k’ is loaded
into the W register.

Example:
MOVLW 0x5A
After Instruction
