I am unable to write STGAP1AS configuration registers

[DSche]

I have a design that uses the STGAP1AS. 2 of the drivers are connected with a spi daisy chain. 

I am able to send read register commands and get expected default values, however i have been unable to write configuration values using the recommended configuration flow on page 49 of the datasheet.

 crc checking is turned off at present. I have not been able to find any detailed application notes, or example code. am I missing something? 

Thanks

wring the configuration registers in a daisy chain configuration requires that the command/crc values be sent for all devices followed by an SS toggle. Then the matching data/crc values are sent followed by another SS toggle

Hi,

I am facing with the same problem with STGAP1AS. Able to read all registers with their default values but I am unable to write to any configuration register despite I followed to recommended configuration flow (datasheet p.49/70).

Did you solve your problem, can you give any information about the solution?

Best,
