N, Z
The contents of register ‘f’ are rotated
one bit to the left. If ‘d’ is ‘ 0 ’, the result
is placed in W. If ‘d’ is ‘ 1 ’, the result is
stored back in register ‘f’ (default).
If ‘a’ is ‘ 0 ’, the Access Bank is selected.
If ‘a’ is ‘ 1 ’, the BSR is used to select the
GPR bank.
If ‘a’ is ‘ 0 ’ and the extended instruction
set is enabled, this instruction operates
in Indexed Literal Offset Addressing
mode whenever f  95 (5Fh). See
Section 29.2.3 “Byte-Oriented and
Bit-Oriented Instructions in Indexed
Literal Offset Mode”

The contents of register ‘f’ are rotated
one bit to the right through the Carry
flag. If ‘d’ is ‘ 0 ’, the result is placed in W.
If ‘d’ is ‘ 1 ’, the result is placed back in
register ‘f’ (default).
If ‘a’ is ‘ 0 ’, the Access Bank is selected.
If ‘a’ is ‘ 1 ’, the BSR is used to select the
GPR bank.
If ‘a’ is ‘ 0 ’ and the extended instruction
set is enabled, this instruction operates
