ADSP 21489 JTAG Connector Debug Agent

Hej all,


I am creating my own board with the ADSP-21489 with 176 Pins. 

I have the EZ Kit with Stand Alone Debug Agent.

On the board are two connectors JTAG P1 and ZP1. For the P1 I know the connections to the DSP from the schematic. But the ZP1 is not included in the schematic. How are the pins of ZP1 connected to the DSP?


I measured the following:

1   5 V supply

2   5 V supply

3   NC (?)

4   3.3 V supply

5   NC (?)

6   Reset

7   NC (?)

8   DA Soft Reset

9 -14  GND


Is this correct?



In the EE-68 document Pin 1 is connected to GND but on the EZ Kit its 5V. 

So I also have to route Pin 1 to 5V?
