ADDWF
ADD WREG to f
Syntax:
[ label ] ADDWF f [,d] [,a]
Operands:
0 ≤ f ≤ 255
d ∈ [0,1]
a ∈ [0,1]
Operation:
(WREG) + (f) → dest
Status Affected: N,OV, C, DC, Z
Encoding:
0010 01da ffff ffff
Description:
Add WREG to register ’f’. If ’d’ is 0,
the result is stored in WREG. If ’d’
is 1, the result is stored back in reg-
ister 'f' (default). If ’a’ is 0, the
Access Bank will be selected. If ’a’
is 1, the Bank will be selected as
per the BSR value.
