Operands:
0
 f  255
d
 [0,1]
a
 [0,1]
Operation:

 dest<n – 1>,
(f<0>)
 dest<7>
Status Affected:
N, Z
Encoding:

00da
ffff
ffff
Description:
The contents of register, ‘f’, are rotated
one bit to the right. If ‘d’ is ‘0’, the result
is placed in W. If ‘d’ is ‘1’, the result is
placed back in register, ‘f’. If ‘a’ is ‘0’,
the Access Bank will be selected, over-
riding the BSR value. If ‘a’ is ‘1’, then
the bank will be selected as per the
BSR value.
