Vcc = 5.0 V,
When a 32-
kHz crystal
resonator is
not used
Notes: 1. This voltage should be used when the falling and rising voltage detection function is
used.
2. Select the low-voltage reset 2 when only the low-voltage detection reset is used.
3. When the power-supply voltage (Vcc) falls below V = 1.0 V and then rises, a reset
LVDRmin
may not occur. Therefore sufficient evaluation is required.
