    Tuning of CY8C21534 CSD user module

      Hi,

         

       

         

      I'm using the CY8C21534 and have a few questions about the tuning process of the capsense CSD user module. Can someone help me with these?

         

      - in the tuning process flowchart ( CY8C21x34/B CapSense® Design Guide page 32 )  it is stated that the SNR should be between 5 and 8. In all other documentation I only found that the minium is 5 with no maximum given. What is the problem if the SNR is higher then 8?

         

      - in that same flowchart the Ref Value is set to 2. In what case should this value be changed to an higher value?

         

       

         

      Thanks.
