EVFLAGS31_0 is shown in Table 15-38.

Return to the Summary Table.

Event Register for DIO 0 to 31
Reading this registers will return 1 for triggered event and 0 for non-triggered events.
Writing a 1 to a bit field will clear the event.
The configuration of events is done inside MCU IOC, e.g. events for DIO #0 is configured in IOC:IOCFG0.EDGE_DET and IOC:IOCFG0.EDGE_IRQ_EN.
