• 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.

• This is a standard 16 pin double row (two rows of 8 pins) connector (pin to pin spacing: 2.54mm/0.100").
• If terminal strip without shroud is used, the spacing marked with "A" must be a minimum of 25.5mm/1".
