PIC12C67X
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 regis-
ter 'f'.

Example
IORWF
RESULT, 0
Before Instruction
RESULT = 0x13
W = 0x91
After Instruction
RESULT = 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.

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 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.

After Instruction
W = value in FSR register
Z= 1
MOVWF Move W to f
Syntax: [
label ] MOVWF f
Operands: 0  f  127
Operation: (W)  (f)
Status Affected: None
Encoding:
00 0000 1fff ffff
Description: Move data from W register to reg-
ister 'f'.

MOVWF OPTION
Before Instruction
OPTION = 0xFF
W = 0x4F
After Instruction
OPTION = 0x4F
W = 0x4F
