4.6.3
These parameters specify the external clock generation for the XC236xA. The clock can
be generated in two ways:
•
•
If connected to CLKIN1, the input signal must reach the defined input levels
If connected to XTAL1, a minimum amplitude
the operation of the on-chip oscillator.
Note: The given clock timing parameters (
