2.3 Pin Functions
The pin functions of the MCUs are described in these subsections.
2.3.1 VDD and VSS
VDD and VSS are the power supply and ground pins. The MCU operates
from a single power supply.
Very fast signal transitions occur on the MCU pins, placing high,
short-duration current demands on the power supply. To prevent noise
problems, take special care, as Figure 2-2 shows, by placing the bypass
capacitors as close as possible to the MCU. C2 is an optional bulk
current bypass capacitor for use in applications that require the port pins
to source high current levels.
