L • Executes scaling for the scaling
conversion data (16-bit data units)
specified by (S2) with the input
value specified by (S1), and then
stores the result into the device
specified by (D). The scaling
conversion is executed based on
the scaling conversion data stored
in the device specified by (S2) and
up.

DSCL • Executes scaling for the scaling
conversion data (32-bit data units)
specified by (S2) with the input
value specified by (S1), and then
stores the result into the device
specified by (D). The scaling
conversion is executed based on
the scaling conversion data stored
in the device specified by (S2) and
