The Frequency Meter (FREQM) can be used to accurately measure the frequency of a clock by
comparing it to a known reference clock.
In order to use this module, other parts of the system must be configured correctly, as described
below.
The device can enter a sleep mode while a measurement is ongoing. However, make sure that
neither CLK_MSR nor CLK_REF is stopped in the actual sleep mode. FREQM interrupts can
wake up the device from sleep modes when the measurement is done, but only from sleep
modes where CLK_FREQM is running. Please refer to the Power Manager chapter for details.
