I/O Name and Function
Input
Power supply: For connection to the
power supply. All V_CC pins should be
connected to the system power
supply.
Input
Ground: For connection to ground
(0 V). All V_SS pins should be
connected to the system power
supply (0 V).
Input
Connects to a crystal oscillator.
See section 18, Clock Pulse
Generator, for typical connection
diagrams for a crystal oscillator and
external clock input.
Input
Connects to a crystal oscillator.
The EXTAL pin can also input an
external clock.
See section 18, Clock Pulse
Generator, for typical connection
diagrams for a crystal oscillator and
external clock input.
Output System clock: Supplies the system
clock to an external device.
