1: Use digital input (from AON) as xosc_lf clock source.
This bit will only have effect when SCLK_LF_SRC_SEL is selecting the xosc_lf as the sclk_lf source. The muxing performed by this bit is not glitch free. The following procedure must be followed when changing this field to avoid glitches on sclk_lf.
1) Set SCLK_LF_SRC_SEL to select any source other than the xosc_lf clock source.
2) Set or clear this bit to bypass or not bypass the xosc_lf.
3) Set SCLK_LF_SRC_SEL to use xosc_lf.
It is recommended that either the rcosc_hf or xosc_hf (whichever is currently active) be selected as the source in step 1 above. This provides a faster clock change.
9CLK_LOSS_ENR/W0hEnable clock loss detection and hence the indicators to the system controller. Checks both SCLK_HF, SCLK_MF and SCLK_LF clock loss indicators.

27-22HPM_UPDATE_AMPR0hXOSC_HF amplitude during HPM_UPDATE state.
When amplitude compensation of XOSC_HF is enabled in high performance mode, this value is the amplitude of the crystal oscillations measured by the on-chip oscillator ADC, divided by 15 mV. For example, a value of 0x20 would indicate that the amplitude of the crystal is approximately 480 mV. To enable amplitude compensation, AON_WUC OSCCFG must be set to a non-zero value.
21-16LPM_UPDATE_AMPR0hXOSC_HF amplitude during LPM_UPDATE state
When amplitude compensation of XOSC_HF is enabled in low power mode, this value is the amplitude of the crystal oscillations measured by the on-chip oscillator ADC, divided by 15 mV. For example, a value of 0x20 would indicate that the amplitude of the crystal is approximately 480 mV. To enable amplitude compensation, AON_WUC OSCCFG must be set to a non-zero value.
