Question about GPIOx_IMR in i.MX6 family

I have a question about GPIOx_IMR in i.MX6 family.

According to the reference manual, when I want to enable a interrupt function, I set the GPIOx_IMR register to "1".



Generally speaking, "Masked" means the function is ignored.

So when I set the register to "1", the interrupt line is masked and the interrupt function is ignored.

I think if my understanding is correct, the description of the reference manual is wrong.

Which is correct?

If the reference manual is correct, what Will be masked ?

Thank you.
