Hi Mike,
The "Appendix A. CoreSight Port List" in [1] documents that many of CoreSight components have a clock signal called 'ATCLK', but I didn't see the description on STM ATCLK. So is there the 'ATCLK' signal on STM too? At what situations the CoreSight components need ATCLK?
Many thanks, Chunyan
