GPIO interrupt

Other Parts Discussed in Thread: OMAP-L138

Dear E2E:

Thank you for your help.

It looks like any GPIO can be setup to generate Interrupt even the function of the particular pin is not GPIO. Is it correct?

Example:

OMAP-L138 PinE4 (GPIO0[0]) is used as ECAP1 APWM output, but GP0[0] can still be used as interrupt (by ECAP1 signal). Is this correct?

Thank you for your help,

Hi,

I don't think it will work that way. Why do you want to use that way?

Regards,

Hyun

Hello Hyun.

Thank you for your respond.

I am asking in general.

It looks like (UM page244 - Pin Multiplexing) nothing can prevent us to set the corresponding GPIO as interrupt even when the OMAP-L138 pin is used for the different function as output.

Is this correct?

Why do you think - it will not work that way?

Thank you for your help,

Bors Ruvinsky
