1. LXT (32768 Hz XTL) ON or OFF depends on SW setting in normal mode.
2. LIRC (10 kHz OSC) ON or OFF depends on S/W setting in normal mode.
3. If TIMER clock source is selected as LIRC/LXT and LIRC/LXT is on.
4. If WDT clock source is selected as LIRC and LIRC is on.
5. If RTC clock source is selected as LXT and LXT is on.
6. If UART clock source is selected as LXT and LXT is on.
