DRV8873: SPI configuration: Error in Reading Data

Part Number: DRV8873

Hi team,

Iam using DRV8873SPWPR Driver IC as in daisy chain mode. 4 Motor driver IC s are connected with MCU.

Data write to the four slaves using the below format,

  • First set the header as 84 and A0 followed by address, for that write operation 04 sent four times after that data(Eg :52) also sent four times.

After that I try to read the data (So the configuration is set by using the same header and make 44 four times for Read operation )

But while reading data , each time I got different data values. Could anyone please help me?

Is the issue is due to not maintain proper delay through software? If yes please let me know how much delay do we need to add for read data after writing.

Warm regards,

Monisha OM
