STM32H563ZI: I3C Hot-join support with STM as I3C Controller

[srinathkp]

Hi,

Suppose I have an I3C target endpoint sending Hot-join request after RSTDAA, is STM32H562/3ZI capable of detecting the Hot-join and pass it on to the firmware layer ? I see Hot-join request support and sample code as an I3C Target in STM32Cube repo on GitHub and generated code. How do we deal with Hot-join request as an I3C Controller

Refer to description about Bit19 HJF of I3C event register (I3C_EVR) shown below, you are allowed to identify Hot-join as I3C controller by checking this bit in your FW. thanks!
