Figure 38-11. ETM Signals
When designing a PCB, it is important to keep the differences between trace length of ETM sig-
nals as small as possible to minimize skew between them. In addition, crosstalk on the trace port
must be kept to a minimum as it can cause erroneous trace results. Stubs on these traces can
cause unpredictable responses, thus it is recommended to avoid stubs on the trace lines.
The TCLK line should be series-terminated as close as possible to the microcontroller pins.
The maximum capacitance presented by the trace connector, cabling and interfacing logic must
be less than 15 pF.
