The release voltage for the LVD module. If a low voltage condition is
detected, the MCU remains in reset until VDDR rises above V_LVRR.
The trip voltage for the LVD module. Depending on its configuration,
various actions can be taken by the LVD module if VDDR falls to V_LVR
level and remains at or below that level.
The Low-Voltage Detector (LVD) module monitors the voltage on the
VDDR pin and can force a reset when the VDDR voltage falls to V_LVR
level and remains at or below that level.
