I am working on AD7758 sag IRQ interrupt activation. If any one have experience in ADE IRQ interrupt on sag your comments will give me good kick start, Expecting your response,
On current design we have three phases to monitor, I am able to read the RMS Voltage values through SPI and I am able to get the frequency reading. Now i am starting my work on SAG interrupt detection for that i am seeking help from your side.
Page 25 - 26 of the data sheet, goes into a lot of detail on how the SAG interrupt works. You have to make sure that the correct bit(s) in the Interrupt Mask Register are set if you want it going to the pin. Or you can read the Interrupt Status Register with or without reset in order to see if the SAG bits are set. You have to read with reset if you want the bit cleared.
