What is the main reason of that the MMA865x has two interrupt outputs?

[hjlim]

MMA865x has two interrupt pins.

Are there special cases that the user should use both channel?

Or is it just for convenience?

Hi HJ,

One interrupt pin is typically used to indicate data-ready for processor synchronization and the second one for any of the embedded functions such as any-motion (slope) detection for wake-up, tap sensing for tap-sensitive user interface control, orientation change recognition for portrait or landscape switching, low-g/high-g detection for shock and free-fall detection, or no-motion for power saving. All these embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data.

Tomas
