Touch sense input (TSI)
48.1 Introduction
The touch sensing input (TSI) module provides capacitive touch sensing detection with
high sensitivity and enhanced robustness. Each TSI pin implements the capacitive
measurement of an electrode having individual programmable detection thresholds and
result registers. The TSI module can be functional in several low power modes with ultra
low current adder and waking up the CPU in a touch event. It provides a solid capacitive
measurement module for the implementation of touch keypad, rotaries and sliders.
