Procedures for Clearing Settings when Using LVDR and LVDI:
To operate or release the low-voltage detection circuit normally, follow the procedure described
below. Figure 18.5 shows the timing for the operation and release of the low-voltage detection
circuit.
1. To operate the low-voltage detection circuit, set the LVDE bit in LVDCR to 1.
2. Wait for 50 s (t
3. To release the low-voltage detection circuit, start by clearing all of the LVDRE, LVDDE, and
have stabilized by a software timer, etc. Then, clear the LVDDF and LVDUF bits in LVDSR
to 0 and set the LVDRE, LVDDE, and LVDUE bits in LVDCR to 1, as required.
LVDUE bits to 0. Then clear the LVDE bit to 0. The LVDE bit must not be cleared to 0 at the
same timing as the LVDRE, LVDDE, and LVDUE bits because incorrect operation may occur.
