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.		2016-06-27 08:11:54 -06:00
