Michael Spahlinger 3d5e690977 Shadow-Mode: The output- and configuration registers of the IO-Expander
are held in the microcontrollers memory and only written to the IO-Expander.
 This reduces bus traffic and is more error-proof than the normal read-
 modify-write operation.

 Retry Mode: If enabled and an error occurs while writing to the IO-Expander the
 current transmission is automatically repeated once.
