Event status of all IOs.
0 : No event has occured on this IO
1 : An event has occured on this IO (an edge as configured in relevant RegSense
register occured).
Writing '1' clears the bit in RegEventStatusA and in RegInterruptSourceA if relevant.
If the edge sensitivity of the IO is changed, the bit(s) will be cleared automatically
Reserved. Must be set to 0 (default value)
