8.
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
multiplexer. 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
conversions 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.
