1.6 Pin Functions

MOTOROLA
Descriptions of the pin functions are provided here.
V
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 special
care to provide power supply bypassing at the MCU as
shows. Place the C1 bypass capacitor as close to the MCU as possible.
Use a high-frequency-response ceramic capacitor for C1. C2 is an
optional bulk current bypass capacitor for use in applications that require
the port pins to source high current levels.
NOTE: Ports PTB4, PTB5, PTC0, and PTC1 are available only with the QFP.
