ARM DSTREAM-PT Reference Manual page 46

1. Although these pins are typically grounded on the target board, the MIPI specification also allows
them to carry power. If they are connected to power rail (or rails) on the target board, these pins must
also be AC coupled to GND using 100nF capacitors that are close to the connector.
2. The TRST_PD signal allows the target board to have a second TAP reset signal which is normally
pulled-down. For more information, see the MIPI debug connector specification.
3. The TRACEEXT signal is not supported by DSTREAM-ST.
Pin 7 must be removed for compatibility with DSTREAM-ST and MIPI specifications.
Using a non-shrouded header on the target board can lead to short-circuits or signal contention. To ensure
the correct polarity and position, Arm recommends that you use a fully shrouded box header.
