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'.

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'.

None
The instruction is supported for code
compatibility with the PIC16C5X
products. Since TRIS registers are
readable and writable, the user can
directly address them.
