The INTSTAT registers provide interrupt status upon reading, and interrupt clear feature upon writing 1 to the corresponding bit position(s). Upon receiving an interrupt, the ISR can examine the interrupt status and clear the processed interrupts.
The GPIO module generates an interrupt pulse on the individual GPINT interrupt in response to each occurrence of the specified edge condition. Therefore, for GPINT signals having their interrupts routed directly to the interrupt controller, it is not necessary to clear the status bits in this module. The interrupt status and clear register is a facility for the per-bank interrupt connection.
