Debugger Connector

Connectors for MPC85XX (PQ3), QorIQ P10XX and P20XX

Connector 16 pin






  • Signals in brackets are not necessary for debugging, but it is recommended to connect those signals if available.
  • Pin 8 will be permanently driven to VCC level by the debugger.
  • Signals which are not available should be left unconnected on the debug connector.
  • Pin 6 (JTAG-VREF) must match the JTAG I/O voltage of the processor. JTAG-VREF should have a resistance less than 5kOhm for 3.0~5.0V, less than 2kOhm for 1.8~3.0V.
  • Debug cables from March 2004 and older (blue ribbon cable, 3.3V..5V only): Pin 6 (VCC) should be directly connected to VCC.
