FUNCTIONAL PIN DESCRIPTION
The following paragraphs give a description of the general function of each pin
assigned in

1.5.1 V
DD
AND V
SS
Power is supplied to the MCU through V
and V
SS
is ground. The MCU operates from a single power supply.
Very fast signal transitions occur on the MCU pins. The short rise and fall times
place very high short-duration current demands on the power supply. To prevent
noise problems, special care should be taken to provide good power supply
bypassing at the MCU by using bypass capacitors with good high-frequency char-
acteristics that are positioned as close to the MCU as possible. Bypassing
requirements vary, depending on how heavily the MCU pins are loaded.
