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: 1
Cycles: 1
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’.
Words: 1
Cycles: 1
Example
: IORWF RESULT, 0
Before Instruction
RESULT = 0x13
W = 0x91
After Instruction
RESULT = 0x13
W = 0x93
Z=0
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.

Cycles: 1
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: 1100 kkkk kkkk
Description: The eight-bit literal ‘k’ is loaded
into the W register.
Words: 1
Cycles: 1
Example
: MOVLW 0x5A
After Instruction
W = 0x5A
