Number of pin interrupts

[djdehaan]

Hi, why is the amount of interrupts limited to 8 (on a nRF52840). In wInterrupt.c it says this and that seems to limitd them to 8:

#if defined(NRF52_SERIES)
#define NUMBER_OF_GPIO_TE 8
#else
#define NUMBER_OF_GPIO_TE 4
#endif

According to my understanding of the hardware, there can be many more interrupts on different pins. I would love to set the max myself, as I understand that number consumes memory as well. Is there another reason why this amount is limited to 8?

The reason for this is because there are only 8 GPIOTE's:
