Name and Function
Power: For connection to the power
supply. Connect the VCC pin to the system
power supply.
Power supply stabilization capacitance:
Connect the VCL pin to the system power
supply together with the VCC pin.
Input/output buffer power: The power
supply for the port A, E, F, and G
input/output buffer.
Ground: For connection to the power
supply (0 V). Connect all VSS pins to the
system power supply (0 V).
Connected to a crystal oscillator. See
section 23, Clock Pulse Generator, for
typical connection diagrams for a crystal
oscillator and external clock input.
Connected to a crystal oscillator. The
EXTAL pin can also input an external
clock. See section 23, Clock Pulse
Generator, for typical connection diagrams
for a crystal oscillator and external clock
input.
