MSP430FR2676: What is the effect of CapTIvate's "Multi-Frequency" on touch performance?

Part Number: MSP430FR2676

1, Which method is advantageous in terms of "SNR" without considering the processing time?

2, Which method is advantageous in terms of "Noise immunity" without considering the processing time?

3, Does "Multi-Frequency with Outlier Removal" not make sense for noise suppression in self-capacitance?

    Hi shunya,

    First, I see you are referencing an older version of Captivate Technology guide v1.10.00.00 which may not include information about the MSP430FR2676.

     v1.83.00.08

    To help provide you with a better answer, can you tell me something about the application (product) and how you are using Captivate?

    For example, something like the following: product is appliance powered from 220vac and has switching power supply operating at or near 2MHz.  The HMI is a 12 button keypad, self capacitive electrodes.
