Hi Malik，

Thank you very much for your reply.

Write 0 or 1 to clear the interrupt ? When the CSR has changed, the interrput pin pulled low, and this bit is 1, so we need to write 0 to clear it ,isn't it ?

Now the question is that our customer wrote 0 to clear it, but it has no effect.

Best regards

Hi Kailyn,

No, customer should write a 1 (1'b1) to clear the interrupt.
