15. Capacitive Sense (CS0)
The Capacitive Sense subsystem uses a capacitance-to-digital circuit to determine the capacitance on a
port pin. The module can take measurements from different port pins using the module’s analog multi-
plexer. The module is enabled only when the CS0EN bit (CS0CN) is set to 1. Otherwise the module is in a
low-power shutdown state. The module can be configured to take measurements on one port pin or a
group of port pins, using auto-scan. A selectable gain circuit allows the designer to adjust the maximum
allowable capacitance. An accumulator is also included, which can be configured to average multiple con-
versions on an input channel. Interrupts can be generated when CS0 completes a conversion or when the
measured value crosses a threshold defined in CS0THH:L.
