SUBLW
Subtract W from literal
Syntax:
[ label ]SUBLW k
Operands:
0
≤ k ≤ 255
Operation:
k – (W)
→ W
Status Affected:
N, OV, C, DC, Z
Encoding:
0000

kkkk
kkkk
Description:
W is subtracted from the eight-bit
literal ‘k’. The result is placed
in W.

SUBWF
Subtract W from f
Syntax:
[ label ] SUBWF
f [,d [,a]]
Operands:
0
≤ f ≤ 255
d
∈ [0,1]
a

Operation:
(f) – (W)

ffff
Description:
Subtract W from register ‘f’ (2’s
complement method). If ‘d’ is ‘0’,
the result is stored in W. If ‘d’ is
‘1’, the result is stored back in
register ‘f’ (default). If ‘a’ is ‘0’, the
Access Bank will be selected,
overriding the BSR value. If ‘a’ is
‘1’, then the bank will be selected
as per the BSR value (default).
