Hi, I am looking for a reference on how the ATCLK (ATB clock, input for the Coresight ITM) is sourced. The Coresight spec allows to source ATCLK by TRACECLKIN or asynchronously. The latter seems to be the case for the Zynq. From which clock is the ATCLK derived?
Is it the "trace_clk" (UG585, table 25-3) or the "TPIU clock" (IP generator forZYNQ7 processing system (5.5))?
