(b) When LVI default start function enabled is set (LVISTART = 1)
Figure 22-6 shows the timing of the internal reset signal generated by the low-voltage detector.
Caution Even when the LVI default start function is used, if it is set to LVI operation prohibition by
Start in the following initial setting state.
When using 8-bit memory manipulation instruction:
When using 1-bit memory manipulation instruction:
When starting operation
When stopping operation
Either of the following procedures must be executed.
Set bit 7 (LVION) of LVIM to 1 (enables LVI operation)
Clear bit 2 (LVISEL) of the low-voltage detection register (LVIM) to 0 (detects level of supply voltage (V
V
Set the low-voltage detection level selection register (LVIS) to 0FH (V
Set bit 1 (LVIMD) of LVIM to 1 (generates reset when the level is detected)
Set bit 0 (LVIF) of LVIM to 0 (“Supply voltage (V
Write 00H to LVIM.
Clear LVIMD to 0 and then LVION to 0.

the software (LVION (bit 7 of LVIM register) = 0), it operates as follows:
This is due to the fact that while the pulse width detected by LVI must be 200 s max.,

reset release. There is a period when low-voltage detection cannot be performed normally,
however, when a reset occurs due to WDT and illegal instruction execution.
LVION = 1 is set upon reset occurrence, and the CPU starts operating without waiting for
the LVI stabilization time.
If a reset is generated while LVION = 0, LVION will be re-set to 1 when the CPU starts after
