<strong>RL78</strong>/<strong>D1A</strong> CHAPTER 24 VOLTAGE DETECTOR<br />

(2) Delay from the time LVD reset source is generated until the time LVD reset has been generated or released<br />

There is some delay from the time supply voltage (VDD) < LVD detection voltage (VLVD) until the time LVD reset has<br />

been generated.<br />

In the same way, there is also some delay from the time LVD detection voltage (VLVD) supply voltage (VDD) until the<br />

time LVD reset has been released (see Figure 24-8).<br />
