Hello,
Would you please provide me with the detail explanation of the purpose and functionality of the following pins

1. DD[1]/ DI[1]

2. DD[0]/ DI[0]

I have deisgned two boards transmitter and receiver using nRF24Z1.

The problem is that I need to monitor the power level of the battery on the transmitter board. If it goes low then I need to send that inofrmation to the Receiver board. Can the above mentioned pins help me to do it?

Thanks

John
