Signal considerations for MPC5XXX/SPC5XX
- Optional signals (leave N/C when unused): RESETOUT-, WDTDIS-, JCOMP, EVTI-, EVTO-, BREQ-, BGRNT-, EXTIO, RDY-
- When the debugger is inactive (SYStem.Mode.DOWN and NoDebug), all output pins are tri-stated (hot-plug capability)
- If the pins EVTI- and EVTO- are assigned to functions other than debugging (e.g. GPIO), do not connect these signals to the debug connector.
- If JCOMP pin is not connected to the debug connector, the processor's JCOMP pin (if implemented) must be tied to VTREF.
- In 1149.7 (cJTAG) mode, following signals change:
- TMS becomes TMSc
- TCK becomes TCKc
- TDI/TDO become N/C (tristated)
- If the 10-pin connector is used:
- Processor external watchdogs have to be disabled (e.g. by jumper)
- Debugging/tracing through reset is not supported for all processors.

Only TriCore AURIX supports JTAG for the 10-pin connector. This variant is not recommended. See the Application Note Debug Cable TriCore for more information.
Signal considerations for TriCore JTAG
- When the debugger is in SYStem.Mode DOWN the RESET- pin is pulled low. In SYStem.Mode NoDebug all output pins are tri-stated (hot-plug capability)
- The OCDS- signal is only required for older TriCore devices, e.g. TC1765, TC1775. For all other devices the signal can optionally be used to disable an external watchdog.
- BRKIN- and BRKOUT- are optional signals not required for debugger operation. In case they are used as regular GPIO pins do not connect them to the debug connector.

Signal considerations for Arm
- TRST- is required if it is available and has a pull-down on target side. Do not connect it otherwise.
- N/C, 'Not Connected' rather means that this pin should not be connected on the target board.
- The trace port of the MIPI20T connector (TRACECLK, TRACEDATA[x]) is not supported with this probe. The signals are ignored.

General Pin and Signal Considerations
- AUTO26/20/10: Pin 7 is a keying pin and has to be removed from the target connector.
- AUTO26: EXTIO (pin 26) is a software configurable input/open-drain-output with a 10k pull-up. Reserved for future use.
- When the debug session is active, the voltage level of a signal driven HIGH matches the voltage level on the VTREF pin.
- VTREF can be connected directly to target VDD, or optional with a serial resistor of 1kOhm or less. It should match the I/O voltage of the debug pins.
- Input impedance on VTREF:
- AUTO26 Whisker for CombiProbe: ~150 kOhm
- AUTO26 Debug Probe V1: ~90 kOhm
- AUTO26 Debug Probe V2: ~10 kOhm
- AUTO26 Debug Probe V3: ~10 kOhm
- All JTAG/DAP output signals of the debug cable have a built-in serial termination of 47 Ohm. The signals should be directly connected to the processor - further termination on the target system is not recommended.
- RESET- is an open-drain output and also input of the debug cable. The debugger drives this pin low to reset the processor. If the RESET- signal is bi-directional, the debugger uses it to detect processor resets.
- RESETOUT- is an input signal to the debug cable. The signal is optional and can be used to detect processor resets, e.g. for processors with separate reset in- and output.
- RESET- and RESETOUT- support a voltage level of max 5V, independent of the VTREF voltage level.
- If the signal TRST-/JCOMP is not available on the used processor/package type, leave the pin on the debug connector unconnected.
