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!

Jim,
