Figure 1-2. Pin Assignments
1.6.1 VDD and VSS
VDD and VSS are the power supply and ground pins. The MCU operates
from a single 5-V 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 to provide good power supply bypassing at
the MCU. Place bypass capacitors as close to the MCU as possible, as
Figure 1-3 shows. C2 is an optional bulk current bypass capacitor for
use in applications that require the port pins to source high current
levels.
