DI
Output Driver Enable Input.
If this pin is asserted Low all analog driver outputs immediately enter a high
impedance mode to support redundancy applications without external
mechanical relays. All other internal circuitry stays active.

RPOL
DI
Receive Polarity Select Input.
Determines RPOS/RNEG polarity.
RPOS/RNEG are active High output polarity when RPOL is High and
active Low polarity when RPOL is Low.
