IORWF
Inclusive OR WREG with f
Syntax:
[ label ] IORWF f [ ,d [,a] ]
Operands:
0 ≤ f ≤ 255
d ∈ [0,1]
a ∈ [0,1]
Operation:
(WREG) .OR. (f) → dest
Status Affected: N,Z
Encoding:
0001 00da ffff ffff
Description:
Inclusive OR WREG with register
'f'. If 'd' is 0, the result is placed in
WREG. If 'd' is 1, the result is
placed back in register 'f' (default).
If ’a’ is 0, the Access Bank will be
selected, overriding the BSR value.
If ’a’ is 1, the Bank will be selected
as per the BSR value.
