Ground: For connection to ground
(0 V). All V_SS pins should be
connected to the system power
supply (0 V).

INPUT Connects an external capacitor
between this pin and the ground pin
(0 V). This pin should never be
connected to V_CC.

Input Connects to a crystal oscillator.
See section 20, Clock Pulse
Generator, for typical connection
diagrams for a crystal oscillator and
external clock input.
78
86
Input Connects to a crystal oscillator.
The EXTAL pin can also input an
external clock.
See section 20, Clock Pulse
Generator, for typical connection
diagrams for a crystal oscillator and
external clock input.
