from a single power supply together with an on chip voltage regulator.
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
shows. Place the bypass capacitors as close to the MCU power pins as
possible. Use high-frequency-response ceramic capacitor for C
C
that require the port pins to source high current level.
