The signal ‘EVTO’
from below connectors can be
pulled up to ‘E0VCC’ via JP28
.
Please refer to the documentation of the used tool, whether this is needed.
The signal ‘TRST’ from below connectors can be pulled up to ‘SYSVCC’ or to the
‘TRST’ line of the used
tool via jumper JP31.
For typical configuration of the jumpers, please refer to
