ADDWFC
ADD W and CARRY bit to f
Syntax:
ADDWFC      f {,d {,a}}
Operands:
 f  255
[0,1]
[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 mem-
ory 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.
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 
 for details.
