PIC16F627A/628A/648A
IORLW
Inclusive OR Literal with W
Syntax:
[ label ]
IORLW k
Operands:
0
≤ k ≤ 255
Operation:
(W) .OR. k
→ (W)
Status Affected:
Z
Encoding:
11
1000
kkkk
kkkk
Description:
The contents of the W register is
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 ≤ 127
d
∈ [0,1]
Operation:
(W) .OR. (f)
→ (dest)
Status Affected:
Z
Encoding:
00
0100
dfff
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
REG1, 0
Before Instruction
REG1 = 0x13
W= 0x91
After Instruction
REG1 = 0x13
W= 0x93
Z= 1
MOVLW
Move Literal to W
Syntax:
[ label ]
MOVLW k
Operands:
0
≤ k ≤ 255
Operation:
k
→ (W)
Status Affected:
None
Encoding:
11
00xx
kkkk
kkkk
Description:
The eight bit literal ‘k’ is loaded
into W register. The “don’t
cares” will assemble as ‘0’s.
Words:
1
Cycles:
1
Example
MOVLW
0x5A
After Instruction
W = 0x5A
MOVF
Move f
Syntax:
[ label ]
MOVF f,d
Operands:
0
≤ f ≤ 127
d
∈ [0,1]
Operation:
(f)
→ (dest)
Status Affected:
Z
Encoding:
00
1000
dfff
ffff
Description:
The contents of register ‘f’ is
moved to a destination
dependent upon the status of
‘d’. If d = 0, destination 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.
Words:
1
Cycles:
1
Example
MOVF
REG1, 0
After Instruction
W = value in REG1 register
Z= 1
