AM335x GPIO Interrupts

Other Parts Discussed in Thread: AM3358

I was looking in the technical reference manual for the AM3358 for the GPIO interrupts. From what I can tell, it look like there is one for GPIO0,1, 2, 3. Does that mean that all the pins on those ports support interrupt capability or are there specific pin in those ports that have the capability?

Thanks

    Yes, all the pins in a GPIO bank can generate an interrupt. All interrupt sources (the 32 input GPIO channels) are merged together to issue two synchronous interrupt requests 1 and 2 per bank. Which pin the interrupt came from is latched in the GPIO_IRQSTATUS_x registers.
