In the first operational mode, the LDC3114 baseline tracking algorithm is enabled and the digital outputs from the two ICs are tied to the button LEDs. Each touch button will correlate to one of the LEDs. Each LDC3114 also uses the MAXWIN feature of the baseline tracking algorithm in this mode. This feature only allows one of the inductive touch buttons on each side of the EVM to report data to the digital outputs at a time.
