d
(f<3:0>)
(f<7:4>)
None
The upper and lower nibbles of regis-
ter '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.

To maintain upward compatibility
with future PIC12C67X products,
do not use this instruction.

(W) .XOR. (f)
Z
Exclusive OR the contents of the W
register with 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'.
