INT_N pin, when there is a trigger event, this pin is temporarily pulled down (for example, pull down 2ms)? Or keep pulling the lower till MCU to handle it?

Hi

The INT_N pin is driven low when at least one interrupt request (IRQ) is active and enabled. Otherwise, the INT_N pin is high-Z.

I know.
But, is INT_N pin driven low for several ms, or it stay pulled down and wait for the MCU to process it?
