d
(f) - (W)
Subtract (2’s complement method) W reg-
ister 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'.

None
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'.

(W)
The instruction is supported for code
compatibility with the PIC16C5X prod-
ucts. Since TRIS registers are read-
able and writable, the user can directly
address them.
