    How to Multiplexing CintA/B as Cmod Cap in PSoC4 (none S series)

    XiaoweiZ_71

      PSoC4000/41XX/42XX/BLE/M/L family parts (PSoC4 none S series) use CSD_V1 CapSense IP, which supports both mutual cap and self cap sensing method. Enable mutual cap and self cap sensing method needs three modulation caps CINTA, CINTB and CMOD.  If IO resources is tight in design´╝îit is possible multiplexing CintA/B as Cmod Cap (parallel CintA anf CintB together and reuse the combined cap as CMOD cap).

       

      Attached sample project shows you how to realize this function in firmware, without change any component generated source code.
