Hi,

we are using AM3359

Can we configure GPIO line as Interrupt line?

If yes, then can we configure it for transition interrupt ( When line goes from High to low)?

If Not, What are the other pins that can be used for transition interrupt ?

Regards,

Bindu

Hi Bindu,

GPIO lines can be configured to generate an interrupt on a high-low or low-high transition via the registers

GPIO_RISINGDETECT and GPIO_FALLINGDETECT.

Does this address your requirement?

Hi Sandhya,

Thanks for the reply.

As i'm new to this processor, where can we find the sample code .

What will be the priority set for these GPIO's?

Bindu
