ADDWFC
ADD WREG and Carry bit to f
Syntax:
[ label ] ADDWFC
f [,d [,a]]
Operands:
0
≤ f ≤ 255
d
∈ [0,1]
a
∈ [0,1]
Operation:
(WREG) + (f) + (C)
→ dest
Status Affected:
N,OV, C, DC, Z
Encoding:

ffff
ffff
Description:
Add WREG, the Carry Flag and data
memory location ’f’. If ’d’ is 0, the
result is placed in WREG. If ’d’ is 1,
the result is placed in data memory
location 'f'. If ’a’ is 0, the Access Bank
will be selected. If ’a’ is 1, the Bank
will be selected as per the BSR value.
