ADE7763 Interrupt not going high

I am using ADE7763 for energy monitoring. I have an issue with the interrupt pin of the device. On power-up it is high as expected.
In order to set ade external interrupt, we send 0x8a, 0x0c, 0x81 in SPI. Once the interrupt happens the pin goes low as mentioned in datasheet. In interrupt code, we clear the interrupt flag and then tried reading the 0x0c, 0x0b and 0x0a registers. But this does not clear the external ADE interrupt (interrupt does not go high). Can you please tell me whether I am skipping any steps or if there is any thing wrong in the steps we followed.
