Using other pins of TSC group as GPIO or Alternate Peripheral Function

Hello All,

I have a doubt. As we know each group of the Touch Sense Controller (TSC) is made of four IO pins. One is used for sense capacitor, leaving behind three for touch sense electrode usage. But if we need to use only one or two of these as an touch sense electrode (touch key pad), can we use the left ones for peripheral function say like Timer channel or usart RX/TX etc?
