XTAL 81 89 Input For connection to a crystal oscillator.
See section 22, Clock Pulse
Generator for typical connection
diagrams for a crystal oscillator and
external clock input.
EXTAL 82 90 Input For connection to a crystal oscillator.
The EXTAL pin can also input an
external clock. See section 22, Clock
Pulse Generator for typical
connection diagrams for a crystal
oscillator and external clock input.
