DRV10983: DRV10983

Part Number:DRV10983

Hello,

I am currently using DRV10983 and trying to communicate with it through I2C using microcontroller. I sent data and clock from Master to DRV10983(slave) but the ack didn't back.

so,

1- what is the perfect timings for delay. 

2-Any advice about why Ack didn't back to master?
