• When starting operation
• When stopping operation
<1> Mask the LVI interrupt (LVIMK = 1).
<2> Clear bit 2 (LVISEL) of the low-voltage detection register (LVIM) to 0 (detects level of supply voltage (V
<3> Set the detection voltage using bits 3 to 0 (LVIS3 to LVIS0) of the low-voltage detection level selection
<4> Clear bit 1 (LVIMD) of LVIM to 0 (generates interrupt signal when the level is detected) (default value).
<5> Set bit 7 (LVION) of LVIM to 1 (enables LVI operation).
<6> Use software to wait for an operation stabilization time (10
<7> Confirm that “supply voltage (V
<8> Clear the interrupt request flag of LVI (LVIIF) to 0.
<9> Release the interrupt mask flag of LVI (LVIMK).
<10> Execute the EI instruction (when vector interrupts are used).
Figure 25-7 shows the timing of the interrupt signal generated by the low-voltage detector. The numbers in this
timing chart correspond to <1> to <9> above.
Either of the following procedures must be executed.
