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

PTC Recommended to use external series resistor
2 Some 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.
