ade7753
I'm from Argentina so apologize me because of my poor english. I could communicate with the ADE7753 but in the datasheet said the when the IC detect a zero crossing a zero appear in the STATUS register and after a read the RSTSTATUS a 1 apear and the IRQ changes to 1. I'm using a a AT89S8253 and i'm programing in ASM, my program set the interrupt vector of the ADE for the zero crossing and the program wait, when the MCU detect the 0 the I read the RSTTATUS but i have a 1 if I read again i have a 0 (this is the Zero crossing flag) , so the question is if the ADE when detect a cero crossing sets a 1 or 0 in the flag?. (the Datasheet said a 0, but i'm detecting a 1)
