Hello.

Help me figure out how the interrupt fired. 

 

I configured interrupt to fire on raising and falling edge with interrupt config parameter:

kGPIO_IntRisingOrFallingEdge

 

In which register  the state of the falling or rising edge is reflected?

 

An one more.

Is it possible to change interrupt settings inside the IRQ function?

For example change kGPIO_IntLowLevel to kGPIO_IntHighLevel.

I tried, but the changes did not work. The interrupt continued to work with the old settings.
