Mode Select Input.
MODE is used to select the type of operating mode the LXT384
Transceiver uses, as shown in the following table.
Note: VCC/2 can be obtained by connecting to a resistive divider
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.
