Write: Data to be output to the output-configured IOs
Read: Data seen at the IOs, independent of the direction configured.

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

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
