Interrupt for PPC405

Hello all,

 

I have a question about the interrupt signal of PPC. In my PPC system, I connected a timer interrupt and a UART interrupt to the OPB_intc controller. The OPB_intc outputs an "irq" to PPC when the peripherals create interrupt signals. For this "irq" signal, how long will it keep "high"?

Cause I know the PPC only supports "level sensitive" interrupt, so is this "high" "irq" reset back to "0" when the PPC completes the related interrupt response program, or not?

 

Thank you!
