Communication Inputs for the Bq wireless power series

Hi,

the bqTesla IC's  have two sets of Comm A  and Comm B  ,  which are recommended to be tied together.

I was wondering what could be the reason for two ports .  Would there be applications where Comm A  and Comm B ports are used seperately,  and what would be this application?

Thanks and Regards,

Ganesh

    The bq500XXX bqTESLA Transmitter Comm A & Comm B are used to read the RX communications packets.  Comm A will demodulate the packets differently for Comm B.  Under some load conditions one works better than the other, result is improved commutations over load.
