from register ‘f’ (2’s complement
method). If ‘d’ is ‘ 0 ’, the result is stored
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 upper and lower nibbles of register
‘f’ are exchanged. If ‘d’ is ‘ 0 ’, the result
is placed in W. If ‘d’ is ‘ 1 ’, the result is
placed in register ‘f’ (default).
If ‘a’ is ‘ 0 ’, the Access Bank is selected.
If ‘a’ is ‘ 1 ’, the BSR is used to select the
