Question

Hello ST export:

This is the first time we've used the L9305 chip in our project. The peripheral hardware circuitry is now all set up. I'd like to know whether ST has a standard recommended initialization procedure for the SPI interface of this chip. (such as who is first for BIST or diagnostic comparators)

And I have another question: the status and results for BIST are in the EXCEPTION1 register D[8:7], is it correct? Shouldn't it be D[10:9]?
