low power timer on the low-frequency clock source (LFCLK).
The RTC will run off the LFCLK. The COUNTER resolution will therefore be 30.517 μs. Depending on the source, the RTC is able to run while the HFCLK is OFF and PCLK16M is not available.
The software has to explicitely start LFCLK before using the RTC.
