1.6 Pin Functions
Description of pin functions are provided here.
1.6.1 Power Supply Pins (VDD, VSS)
VDD and VSS are the power supply and ground pins. The MCU operates
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 care to
provide power supply bypassing at the MCU as shown in Figure 1-3.
