Master clock input pin
Connect a crystal oscillator between this pin and the XTO pin, or input the
external CMOS clock signal XTI pin. The clock frequency
can be selected by the CKS0 and CKS1 pins.
Crystal oscillator output pin
When a crystal oscillator is used, connect it between the XTI pin and this pin.
When the external clock is used, keep this pin open.
