I'm using mma8453 accelerometer in a current project I'm working on.
I'm setting the interrupt INT 1 to be active low (once setting I can see in the oscilloscope that the INT 1 line is high).
As soon as I finish the rest of the configurations I detect an interrupt, and to clear the interrupt I read the register INT_SOURCE, but I read all 0's, ie. no interrupt to be handled.
looking at the oscilloscope I can see the INT 1 line is now low. and stays low.
I wonder what might be the cause for that and how can I force clean the interrupt line?
Thanks in advance,
