The capacitive sensing module allows for an interaction
with an end user without a mechanical interface. In a
typical application, the capacitive sensing module is
attached to a pad on a printed circuit board (PCB), which
is electrically isolated from the end user. When the end
user places their finger over the PCB pad, a capacitive
load is added, causing a frequency shift in the capacitive

sensing module. The capacitive sensing module
requires software and at least one timer resource to
determine the change in frequency. Key features of this
module include:
• Analog MUX for monitoring multiple inputs
• Capacitive sensing oscillator
• Multiple timer resources
• Software control
• Operation during Sleep
