Subtract W from f
[ label ]
0 ≤ f ≤ 127
d ∈ [0,1]
(f) - (W) → (dest)
C, DC, Z
00
Subtract (2’s complement method)
W register from register ‘f’. If ‘d’ is
‘0’, the result is stored in the W
register. If ‘d’ is ‘1’, the result is
stored back in register ‘f’.

TRIS
Load TRIS Register
[ label ] TRIS
5 ≤ f ≤ 7
(W) → TRIS register f;
None
00
The instruction is supported for
code compatibility with the
PIC16C5X products. Since TRIS
registers are readable and
writable, the user can directly
address them.

To maintain upward compatibil-
ity with future PIC
products, do not use this
instruction.
Swap Nibbles in f

0 ≤ f ≤ 127
d ∈ [0,1]
(f<3:0>) → (dest<7:4>),
(f<7:4>) → (dest<3:0>)
None
00
The upper and lower nibbles of
register ‘f’ are exchanged. If ‘d’ is
‘0’, the result is placed in W
register. If ‘d’ is ‘1’, the result is
placed in register ‘f’.
