DRV8316C: CSx setting

Part Number: DRV8316C

Hello Experts,

My customer has question as follows. Would you answer it, please?
[Question]
What I would like to confirm is the current detection value output function of the DRV8316C.
This function may output the current detection value multiplied by the gain from SOA, B, and C. It is not reflected in the output.
The specific register is "CSA_gain" in "Control Register 5".
The register value can be changed in SPI, and the changed value can be read by performing Read. However, no matter which value is set, it works at the initial value (0x0). (Checked from the output value) is there any action or register setting that is necessary after changing the setting?

All setting values other than this register are the initial values except "slew" in "Control Register2".
* The "slew" setting of "Control Register2" is output (OUTA, B, C).

Best Regards,
Fujiwara
