14-Pin 2.54Mm Jtag Converter - iSystem Aurora MPC5 Series User Manual

14-pin 2.54mm JTAG Converter

Ordering code
If your target features 14-pin 2.54mm pitch JTAG target debug connector, use iSYSTEM 14-pin
2.54 mm JTAG Adapter which acts as a pinout converter. The adapter must be ordered
separately. The adapter can be used only in conjunction with the iC6000 DTM Aurora/JTAG
module (IC60022-1).
The following pinout is valid on the target side:

Mandatory pins on the microcontroller side are GND, VDD, RESET, TMS, TDI, TDO and TCK.
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
connector, it must be set to the non-active state in the target via a pull-up resistor. If not then
the JTAG TAP state machine remains in reset and debugging is not possible.
