The voltage detection circuit (LVD) is only supported by the H8SX/1665M Group.
This circuit is used to monitor Vcc. The LVD is capable of internally resetting the LSI when Vcc
falls and crosses the voltage detection level. An interrupt can also be generated.

A block diagram of the voltage detection circuit is shown in figure 5.1.
Capable of detecting the power-supply voltage (Vcc) becoming less than or equal to Vdet.
Capable of generating an internal reset or interrupt when a low voltage is detected.
