Microchip Information

11 EFT

EFT noise is injected into the power lines and therefore EFT is not a touch-specific issue. EFT can cause the MCU to behave erratically and therefore influence touch. Refer to the "EMI, EMC, EFT, and ESD Circuit Design Consideration for 32-bit Microcontrollers Application Note" document for detailed information on preventing EFT failures.
