10.2 Instruction Descriptions
ADDLW Add Literal and W
Syntax: [
label ] ADDLW k
Operands: 0  k  255
Operation: (W) + k  (W)
Status Affected: C, DC, Z
Encoding:
11 111x kkkk kkkk
Description: The contents of the W register are
added to the eight bit literal 'k' and
the result is placed in the W regis-
ter.
Words: 1
Cycles: 1
Example
ADDLW 0x15
Before Instruction
W = 0x10
After Instruction
W = 0x25
ADDWF Add W and f
Syntax: [
label ] ADDWF f,d
Operands: 0  f  127
d 
Operation: (W) + (f)  (dest)
Status Affected: C, DC, Z
Encoding:
00 0111 dfff ffff
Description: Add the contents of the W register
with register 'f'. If 'd' is 0, the result
is stored in the W register. If 'd' is
1, the result is stored back in reg-
ister 'f'.
