Blue colored signals are Aurora trace signals.
The JCOMP is an optional pin. Some microcontrollers don't have this pin. Internally, this is
actually the JTAG TRST which resets the JTAG TAP state machine. Because the JTAG TAP
state machine can be reset also by the TMS and the TCK, this pin is optional also for the
debugger. If the microcontroller has the JCOMP pin but it is not connected to the target debug
