MPC5634M BAM pin129

Dear Support Team:

 

My customer is using MPC5634M BAM module to load their application code into internal flash through CAN bus. Pin129 is used as a GPIO drive some external circuit with a pull-down resistor to ground.

 

So far everything works fine if the pull-down resistor is 100K Ohm.
However we could not connect to the micro if the pull-down resistor is changed to 10K Ohm.

 

Since pin129 is multiplexed with NEXUS EVTO function, we are not sure if there is any conflict. And according to datasheet, this function is not available on 176LQFP package.

 

Could you help to check if extra attention should be paid here?
Your quick response would be highly appreciated!

 

Best Regards,
Wang.
