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
3. Place the C1 bypass capacitor as close to the MCU as possible. Use
a high-frequency response ceramic capacitor for C1. C2 is an optional
bulk current bypass capacitor for use in applications that require the port
pins to source high current levels.
