Supply voltage (V
<To start operation>
<1> Mask the interrupt of the low-voltage detector (LVI).
<2> Select the voltage to be detected by using the LVIS.LVIS0 bit.
<3> Set the LVIM.LVION bit to 1 (to enable operation).
<4> Insert a wait cycle of 0.1 ms or more by software.
<5> By using the LVIM.LVIF bit, check if the supply voltage > detection voltage.
<6> Clear the interrupt request flag of LVI.
<7> Unmask the interrupt of LVI.
<To stop operation>
Set the LVION bit to 0.
