    About behavior of LVD on FM3 / FM4

    SuSh_1535366

      Hello,

       

      I have some questions about the behavior of FM3 / FM4.

       

      1. For example, turn on the power and set LVD detection voltage to 3.9V.
          If the supply voltage only rises to 3.5 V, does an interrupt occur when the LVD interrupt is enabled?

          (When the power supply voltage never exceeds 4V)

       

      2. Is there a simple way to check that the power supply voltage has exceeded the release voltage from the above conditions?

       

      3. After clearing the LVD interrupt request, if the power supply voltage rises above the release voltage, does the interrupt occur again in the low voltage state?

       

      Teach me please

       

      Regards,
