from a single power supply.
Very fast signal transitions occur on the MCU pins, placing high,
short-duration current demands on the power supply. To prevent noise
problems, take special care as
capacitors as close as possible to the MCU. C2 is an optional bulk
current bypass capacitor for use in applications that require the port pins
to source high current levels.
