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 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’.
