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 regis-
ter.
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' are
moved to destination 'd'. If 'd' is 0,
destination is the W register. If 'd'
is 1, the destination is file register
'f'. 'd' = 1 is useful as a test of 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:
1100 kkkk kkkk
Description: The eight bit literal 'k' is loaded into
the W register. The don’t cares
will assembled as 0s.
