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
as close to the MCU power pins as possible. Use high-frequency-response
ceramic capacitors for C
for use in applications that require the port pins to source high-current levels.
