Hi@sephangie

   for example , create an interrupt for Port D(GPIO).

INT_SYS_InstallHandler(PORTD_IRQn, &PortD_Extern_ISR,  (isr_t*) 0);
INT_SYS_EnableIRQ(PORTD_IRQn);


void PortD_Extern_ISR(void)
{
 PINS_DRV_ClearPortIntFlagCmd(PORTD);
}

 There are many routines in the official SDK , for details, you can refer to the routines.

BR!
