The maximum CLKOUT frequency is limited by the driver capability of the CLKOUT/RXD
pin and depends on the external load connected to this pin. Please be aware that large
loads and/or high clock frequencies at this pin may interfere with the receiver and reduce
performance.
After Reset the CLKOUT/RXD pin is activated and the division factor initialized to 7
(equals 1 MHz for f
A higher clock output frequency than 1 MHz is not recommended.
