Dear All,

 

Hello.

I have a question about more than one GPIO interrupt in i.MX6DQ.

 

[Q1]

We will use the GPIO3_IO18 port (from external MCU) and GPIO3_IO31 port (from AUX audio) and set the GPIO3_GDIR/GPIO3_ICR2/GPIO3_IMR registers.

If above two interrupts input at the same time, How does the condition of GPIO3_ISR change? (I think It's very rare case.)

 

[Q2]

If above two interrupts input at the same time, Is two interrupt processings executed?

(We worry, that another interrupt is ignored.)

 

OS:L3.14.28_1.0.0

 

Best Regards,

Keita
