Hi,

I am working on NUCLEO-H533RE board. I am checking all the configurations before start of my work. As attached below, The datasheets says that PKA is supported when i opened .ioc file, It is visible as greyout. I am not able to activate it. Even i configured the clock configurations for the board. I am not able to find documentation regarding H533RE. mostly it was written about H563 or H573 series. Could you please also help me out regarding the documents.
