Hi i am david park


I am using a ADE7880.


I set ZXVA bit in MASK1 Register. and I have supplied to VAP source.


and then ZXVA bit in STATUS1 Register have worked well. but IRQ1 have not worked.(the IRQ1 interrupt pin is not driven low)


so now I am checking zero crossing detection by reading STATUS1' ZXVA bit.


of course. as soon as i read STATUS1. The status bit is cleared by writting  to the STATUS1 register with the status bit set to 1.


Do you have any solution or checking point about this problem?


Best regards!
