These bits are always read as 1, and cannot be modified.
LVDR Detection Level Select
0: Reset detection voltage is 2.3 V (typ.)
1: Reset detection voltage is 3.6 V (typ.)
When the falling or rising voltage detection interrupt is
used, reset detection voltage of 2.3 V (typ.) should be
used. When only a reset detection interrupt is used, reset
detection voltage of 3.6 V (typ.) should be used.
