The contents of W are OR’ed with
the eight-bit literal ‘k’. The result is
placed in W.

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