Description:
The contents of the W register is
OR’ed with the eight bit literal 'k'.
The result is placed in the W
register.

Example
IORLW
0x35
Before Instruction
W = 0x9A
After Instruction
W = 0xBF

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'.

Example
MOVLW
0x5A
After Instruction
W = 0x5A
MOVF

dfff
ffff
Description:
The contents of register f is
moved to a destination depen-
dent upon the status of d. If d =
0, destination is W register. If d
= 1, the destination is file regis-
ter f itself. d = 1 is useful to test
a file register since status flag Z
is affected.

After Instruction
W= value in REG1 register
Z = 1
