DM6446 Intrerrupt Detection

g.f.

Hi,

I have a question about Davinci DM6446 interrupt.
How DM6446 ARM core detect the interrupt?
Does ARM core detect interrupt by edge or level of the interrupt signal?

I have one more question.
Does DM6446 have any internal circuit for reducing noise and chatter?

Best regards,

ARM detects the interrupt using IRQ line which is connected to the ARM core from AINTC interrupt controller inside Davinci.

What kind of noise/chatter are you referring to?

Thomas,
Thank you for your response.

We were thinking about the noise which occurs in the exterior of a davinci.
But we got information that we need to take care of the noise
at exterior of a davinci.

Best regards,
