signal (LVIRES) is generated.
23.4.1 To use for internal reset signal
1044
Depending on the setting of the LVIM.LVIMD bit, an interrupt request signal (INTLVIL, INTLVIH) or an internal reset
<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> Set the LVIM.LVIMD bit to 1 (to generate an internal reset signal).
Caution If the LVIMD bit is set to 1, the contents of the LVIM and LVIS registers cannot be changed until a
reset request other than the low-voltage detector (LVI) is generated.
