Hello,

I am working on detecting  the SAG level in ADE7880,

I set SAG_CYC to 0x04,then SAG theshold to 0x207269 which corresponds to 100VAC,

I configured IRQ1 interrupt the MASK1 SAG1 bit is set to 1,

i get following result

i) I get interrput sometimes when count falls below 0x13F500 which is around 70VAC,

but when in read the STATUS1 register on IRQ1 interrupt,the SAG = 0,

I am not getting resutls as expected as told in the datasheet of ADE7880,

Please help me on this thanks
