Configures direction for each IO.
0 : IO is configured as an output
1 : IO is configured as an input

Configures which [input-configured] IO will trigger an interrupt on NINT pin
0 : An event on this IO will trigger an interrupt
1 : An event on this IO will NOT trigger an interrupt
Configures which [input-configured] IO will trigger an interrupt on NINT pin

Interrupt source (from IOs set in RegInterruptMaskB)
0 : No interrupt has been triggered by this IO
1 : An interrupt has been triggered by this IO (an event as configured in relevant
RegSense register occured).
Writing '1' clears the bit in RegInterruptSourceB and in RegEventStatusB
When all bits of both RegInterruptSourceA/B are cleared, NINT signal goes back high.
Interrupt source (from IOs set in RegInterruptMaskA)
0 : No interrupt has been triggered by this IO
1 : An interrupt has been triggered by this IO (an event as configured in relevant
RegSense register occured).
Writing '1' clears the bit in RegInterruptSourceA and in RegEventStatusA
When all bits of both RegInterruptSourceA/B are cleared, NINT signal goes back high.
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 RegEventStatusB and in RegInterruptSourceB if relevant.
If the edge sensitivity of the IO is changed, the bit(s) will be cleared automatically
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)
