[quote user="Biser Gatchev-XID"]Interrupts for the GPIO channel must be enabled in the GPIO_IRQSTATUS_SET_0 and/or GPIO_IRQSTATUS_SET_1 registers.[/quote]
OK, this specifies if interrupt line 0 or 1 has to be used.
[quote user="Biser Gatchev-XID"]The expected event(s) on input GPIO to trigger the interrupt request has to be selected in the GPIO_LEVELDETECT0, GPIO_LEVELDETECT1, GPIO_RISINGDETECT, and GPIO_FALLINGDETECT registers.[/quote]
This specifies if an interrupt has to happen on LOW, level, HIGH level, rising edge or falling edge but does not give the possibility to assign one of the events to a specific interrupt line.
So for me also this part of manual does not describe why there are two interrupt lines when they can't be used for different events.
