Crystal connection or external reference frequency input. This pin has dual functions. It
can be connected either to an external crystal or an external reference clock.
Crystal connection. If using an external reference, this pin must be left unconnected.
When SSON is HIGH, the spread spectrum is enabled and when LOW, it turns off the
spread spectrum. Connect the pin to ground When Spread Spectrum feature is not
required.
No connect.
Ground connection.
Spread spectrum clock output.
No connect.
