J-Link / J-Trace (UM08001)
The following table show different names for the trace signals depending on the ETM
architecture version.
Table 8.6: Assignment of trace information pins between ETM architecture versions
Data transfer is synchronized by TRACECLK.
The maximum capacitance presented by J-Trace at the trace port connector,
including the connector and interfacing logic, is less than 6pF. The trace port lines
have a matched impedance of 50.
The J-Trace unit will operate with a target board that has a supply voltage range of
3.0V-3.6V.
For capturing trace port signals synchronous to TRACECLK, J-Trace supports
a TRACECLK frequency of up to 200MHz. The following table shows the TRACECLK
frequencies and the setup and hold timing of the trace signals with respect to TRACE-
CLK.
