SWAPF
Swap nibbles in f
Syntax:
[ label ] SWAPF f [ ,d [,a] ]
Operands:
0 ≤ f ≤ 255
d ∈ [0,1]
a ∈ [0,1]
Operation:
(f<3:0>) → dest<7:4>,
(f<7:4>) → dest<3:0>
Status Affected: None
Encoding:
0011 10da ffff ffff
Description:
The upper and lower nibbles of reg-
ister ’f’ are exchanged. If ’d’ is 0, the
result is placed in WREG. If ’d’ is 1,
the result is placed in register ’f’
(default). If ’a’ is 0, the Access
Bank will be selected, overriding
the BSR value. If ’a’ is 1, the Bank
will be selected as per the BSR
value.
