Description:
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’.

The instruction is supported for
code compatibility with the
PIC16C5X products. Since TRIS
registers are readable and writ-
able, the user can directly
address them.
