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
to provide good power supply
bypassing at the MCU. Place
bypass capacitors as close to the
MCU as possible, as shown in
