The RTC can be used to wake the CC23xx device from any state where the RTC is active. The RTC
contains one capture and one compare channel. With software support, the RTC can be used
for clock and calendar operation. The RTC is clocked from the 32 kHz RC oscillator or
the 32 kHz crystal oscillator. The CLKLF period is measured in hardware and the
resulting LFINC is used to increment RTC time on every CLKLF edge.
