2.1 VDD and VSS
Power is supplied to the MCU through VDD and VSS. VDD is the power supply, and
VSS is ground. The MCU operates from a single 5-volt (nominal) power supply. Very
fast signal transitions occur on the MCU pins. The short rise and fall times place high,
short duration current demands on the power supply. To prevent noise problems, pro-
vide good power-supply bypassing at the MCU. Also, use bypass capacitors that have
good high-frequency characteristics and situate them as close to the MCU as possible.
Bypass requirements vary, depending on how heavily the MCU pins are loaded.
