Beahvior when disabled interrupt occurs.

Jun Ito(AW)

Hi,

For the interrupt that is not used, we disables the interrupt and does not set the interrupt handler through Hwi_create().
However, if the above interrupt occurs for any reason, how the process is going?
(Going out of control?, going to busy loop?, etc.)

It situation is difficult to happen. But we are concerning about the behavior.

Best regards,

Hi Ito,

What device are you using ?

In general, if an interrupt has been explicitly disabled then the interrupt handler will not be called even if the interrupt occurs.

Hi Ashish,

I'm sorry lack of information. I'm using DRA814x. Thank you for your answer,

My understanding is as follows:

In other word, If we do not set the interrupt handler and interrupt happen, nothing happen. Is it correct?

Best regards,

Ito

Yes, If you never register an interrupt (i.e. do a Hwi_create() for a particular interrupt) then it will be cleared and disabled at startup and will not be triggered even if the interrupt occurs.
