ACQ — Not in Acquisition
PSTP — Pseudo-STOP Enable
LHIE — Limp-Home Interrupt Enable
NOLHM —No Limp-Home Mode
If AUTO = 1 (ACQ is Read Only)
If AUTO = 0
In Pseudo-STOP mode, the oscillator is still running while the MCU is
maintained in STOP mode. This allows for a faster STOP recovery
and reduces the mechanical stress and aging of the resonator in case
frequent STOP conditions at the expense of a slightly increased
power consumption.
Forced to 0 when VDDPLL is at VSS level.
Read anytime; Normal modes: write once; Special modes: write
anytime. Forced to 1 when VDDPLL is at VSS level.

0 = PLL VCO is not within the desired tolerance of the target
1 = After the phase lock loop circuit is turned on, indicates the PLL
0 = High bandwidth PLL loop selected
1 = Low bandwidth PLL loop selected
0 = Pseudo-STOP oscillator mode is disabled
1 = Pseudo-STOP oscillator mode is enabled
0 = Limp-Home interrupt is disabled
1 = Limp-Home interrupt is enabled
0 = Loss of reference clock forces the MCU in limp-home mode.
1 = Loss of reference clock causes standard Clock Monitor reset.
