TSS Key detection failure

Dear Folks,

I am using KL05Z Microcontroller and TSSv3.1 for recognising touch Inputs, I have configured the touch detection through the TSI method.

 

Normallay my application works fine but once in a while a particular key is not detected , I checked the signal on the oscilloscope when the key recognation stops , there is no Signal generated for that particular key but all the other keys function normally.

 

On restart of the µC again everything is normal.

 

I just checked with the stuck key configuration , but i see that stuck key is used to recognise the state high condition (a constant high Input at the key) .

 

Questions

1) Why does the Signal Generation stop only for one key from the µc

2) Are there ways to recognise such a condition in TSS and re initialize the TSS module.

 

Best regards,

Suresh Jaggal.
