*5: This detection voltage level setting is below the minimum operation assurance voltage (2.7V*4 or
4.0V*3) .Between this detection voltage and the minimum operation assurance voltage,
MCU functions are not guaranteed except for the low voltage detector.
Note that although the detection level is below the minimum operation guarantee voltage,
the LVD reset factor flag is set as the voltage drops below the detection level.

*5: These LVD settings cannot be used to reliably generate a reset before voltage dips below minimum
guaranteed MCU operation voltage, as these detection levels are below the minimum guaranteed MCU
operation voltage(2.7V).
