PEAK VOLTAGE DETECTION The ADE7758 can record the peak of the voltage waveform and produce an interrupt if the current exceeds a preset limit. ADE7758은 전압 파형의 피크값을 기록할 수 있으며 전류가 기정의 한계값을 초과하게되면 인터럽트를 발생할 수 있다. Peak Voltage Detection Using the VPEAK Register The peak absolute value of the voltage waveform within a fixed number of half-line cycles is stored in the VPEAK register. Figure 58 illustrates the timing behavior of the peak voltage detection. 반-선형 사이클의 고정수내의 전압 파형의 피크 절대값은 VPEAK 레지스터에 기록된다. 그림58은 피크 전압 검출의 타이밍 상태를 표현한 것이다. Note that the content of the VPEAK register is equivalent to Bit 6 to Bit 13 of the 16-bit voltage waveform sample. At full-scale analog input, the voltage waveform sample at 60 Hz is 0x2748. The VPEAK at full-scale input is therefore expected to be 0x9D. In addition, multiple phases can be activated for the peak detection simultaneously by setting multiple bits among the PEAKSEL[2:4] bits in the MMODE register. These bits select the phas
