Note
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), the
DSTREAM-ST unit can support separate debug and trace VTREFs. If only TRACE_VTREF is
powered, the DSTREAM-ST unit assumes that both debug and trace are to operate at that voltage.
3. These signals are not used by the DSTREAM-ST unit. To maintain compatibility with other debug
units, connect the signals to the appropriate power rails.
4. The TRACECTL signal is not currently supported by the DSTREAM-ST unit because only
continuous-mode TPIU trace is supported.
