Content of LPS22DF i3c IBI payload?

I have an LPS22DF sensor connected via I3C. I can enable I3C in-band-interrupts (IBIs), and see the IBIs occur on data-ready events.

I see the IBIs have a 5-byte data payload, but I can't find any definition of the data in this payload. Is this described somewhere? Is the PEC byte present?

Hi @Jeremy Kerr​ ,

Welcome to ST Community!

The 5 bytes are according to MIPI specification where the first byte is mandatory data byte and the rest of the payload is decoded according to MIPI specification guidelines for timing control modes or just they are decoded according to MIPI specification guidelines.

What do you mean as PEC byte?
