Description
The on-chip circuit is used to generate the reference voltage
The reference voltage is input to the Vref pin from an external source
Description
[Clearing condition]
When 0 is written after reading 1
[Setting condition]
When the power supply voltage drops below Vint(D)
Description
[Clearing condition]
When 0 is written after reading 1
[Setting condition]
When the power supply voltage drops below Vint(D) while the LVDUE bit in
LVDCR is set to 1, and it rises above Vint(U) before dropping below Vreset1
