When the power-supply voltage falls below Vint (D)
(Typ. = 3.7 V)
When writing 0 to this bit after reading it as 1
When the power supply voltage falls below Vint (D)
while the LVDUE bit in LVDCR is set to 1 and then
rises above Vint (U) (Typ. = 4.0 V) before falling
below Vreset1 (Typ. = 2.3 V)
When writing 0 to this bit after reading it as 1
