Signal considerations for MPC5XXX/SPC5XXX

  • 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.

General Pin and Signal Considerations

  • AUTO26/20/10: Pin 7 is a keying pin and has to be removed from the target connector.
  • AUTO26/20/10: 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: ~50 kOhm (to be confirmed)
  • 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.
