9This sample is a minimum application to demonstrate how to output one of the internal clocks for
10external use by the application.

15The SoC should support MCO functionality and use a pin that has the MCO alternate function.
16To support another board, add an overlay in boards folder.
17Make sure that the output clock is enabled in dts overlay file.

28After flashing, the LSE clock will be output on the MCO pin enabled in Device Tree.
29The clock can be observed using a probing device, such as a logic analyzer.
