Description
LVD Power-Supply Voltage Rise Flag
[Setting condition]
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)
[Clearing condition]
When writing 0 to this bit after reading it as 1
