from a single power supply.
Fast signal transitions on MCU pins place high, short-duration current
demands on the power supply. To prevent noise problems, take special
care to provide power supply bypassing at the MCU as shown in

is an optional bulk current bypass capacitor for use in applications that
require the port pins to source high current levels.
