ADDWFC ADD W and Carry bit to f
Syntax: [ label ] ADDWFC f [,d [,a]]
Operands: 0  f  255
d [0,1]
a [0,1]
Operation: (W) + (f) + (C)  dest
Status Affected: N, OV, C, DC, Z
Encoding: 0010 00da ffff ffff
Description: 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 will be selected. If ‘a’ is ‘1’,
the BSR will not be overridden.
