LVI is monitored on the VDDA supply domain
LVRX is monitored on the VDDX supply domain only active during full performance mode. During reduced performance
The ACLK trimming must be set that the minimum period equals to 0.2ms

mode (stopmode) voltage supervision is solely performed by the POR block monitoring core VDD.
The LVR monitors the voltages VDD, VDDF and VDDX. If the voltage
drops on these supplies to a level which could prohibit the correct function
(e.g. code execution) of the microcontroller, the LVR triggers.
