ADDWFC
ADD W and Carry bit to f
Syntax:
Operands:
Operation:
[ label ] ADDWFC f [,d [,a]
0  f  255
d [0,1]
a [0,1]
(W) + (f) + (C)  dest
Status Affected:
Encoding:
Description:
Words:
N,OV, C, DC, Z
0010 00da ffff ffff
Add W, the Carry Flag and data
memory location 'f'. If 'd' is 0, the
result is placed in W. If 'd' is 1, the
result is placed in data memory loca-
tion 'f'. If ‘a’ is 0, the Access Bank
will be selected. If ‘a’ is 1, the BSR
will not be overridden.
