External Clock Drive XTAL1
Note: If the on-chip oscillator is used together with a crystal, the oscillator frequency is
limited to a range of 4 MHz to 16 MHz.
It is strongly recommended to measure the oscillation allowance (or margin) in the
final target system (layout) to determine the optimum parameters for the oscillator
operation. Please refer to the limits specified by the crystal supplier.
When driven by an external clock signal it will accept the specified frequency
range. Operation at lower input frequencies is possible but is guaranteed by
design only (not 100% tested).
