1. The measuring condition is Vcc=AVcc=2.7V to 5.5V and Topr=-40°C to 85°C.
2. This shows the time until the voltage detection interrupt request is generated since the voltage passes Vdet.
3. This shows the required time until the voltage detection circuit operates when setting to "1" again after setting the VC27 bit in the VCR2
