ARM DSTREAM-PT Reference Manual page 41

1. The EXTTRIG signal is deprecated and not supported by Arm Development Studio.
2. Although the Arm CoreSight specification only supports a single VTREF (on pin 12), DSTREAM-
ST can support separate debug and trace VTREFs. If only TRACE_VTREF is powered, the
DSTREAM-ST assumes that both debug and trace are to operate at that voltage.
3. These signals are not used by DSTREAM-ST. To maintain compatibility with other debug units,
connect the signals to the appropriate power rails.
4. The TRACECTL signal is not currently supported by DSTREAM-ST because only continuous-
mode TPIU trace is supported.
