Mode Select Input.
MODE is used to select the type of operating mode the
LXT384 Transceiver uses, as shown in the following table.
Note:
For details on modes in the table, see the following:
Multiplexed/Non-Multiplexed Select Input.
When the LXT384 Transceiver is in parallel interface host processor
mode, and MUX is:
In hardware mode, tie this unused input low.
