When PTC is used in Self-Capacitance mode, the internal series resistor is not effective in reducing noise.

PTCRecommended to use external series resistor
2Some pins have higher parasitic capacitance. Refer to the “Device Pin Capacitance” sheet of https://microchip.wdfiles.com/local--files/touch:release-notes/QTouch_PTC_Information_7.1.xlsx for details.PTC
  1. Avoid these pins if alternate Y lines are available.
  2. If it is required to use this pin for touch, then higher charge-time needs to be provided which might impact response time.
