TPIU Trace Clock How to Configure for ETM Tracing

Hi,

Is there a simple way to configure the TPIU trace clock for ETM trace capture pls? This is for a Cortex M33 and the traceclk will vary (depending on CPU clock and power saving) so we will need to configure the TPIU clock via DAP I guess?

Wasnt sure if this was something that ARM DS will support.

Thanks
