Up to 48 input sources to be selected from according to the

3 is selected.
(Analog Switch) Selects an input equal to the value of the
ANALOG SELECT parameter.
(Discrete Switch) Selects Input #1 or #2 according to state of
DISCRETE SELECT.
Example: if ASEL=3, then Input #3 is selected. If ANALOG
SELECT < 1, Input #1 is selected. The value of ANALOG
SELECT is truncated to a whole number. For example, if
ANALOG SELECT is 3.55, the value is truncated to 3 and
Input #3 is selected.
