I have connected TI controller as Master and LTC6812 as slaves on SPI.

Only 4 signals are connected to AFE namely CLK,MISO,MOSI , Data from master.

I can see that MISO,MOSI and CLK are correct but the data begins to receive data but not complete.

How do I check the AFE is working properly with TI

1. Send a wake up pulse on the CS line - Check the voltage on the VREG pin it should be 5V

2. Do a write and read of configuration registers and check if you are able to read from the deivice the same data what you wrote.

- Follow the device protocols as mentioned in the datasheet
