ADD W and Carry bit to f
ADDWFC f {,d {,a}}
0  f  255
d [0,1]
a [0,1]
(W) + (f) + (C)  dest
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 location ‘f’.
If ‘a’ is ‘0’, the Access Bank is selected.
If ‘a’ is ‘1’, the BSR is used to select the
GPR bank (default).
If ‘a’ is ‘0’ and the extended instruction
set is enabled, this instruction operates
in Indexed Literal Offset Addressing
mode whenever f 95 (5Fh). See
Section 28.2.3 “Byte-Oriented and
Bit-Oriented Instructions in Indexed
Literal Offset Mode” for details.
