During initialization a subset of registers have to be programmed to set the configuration
parameters according to the application and desired features. They are listed in table 15.
After reset, the ISAC-S TE is in IOM-1 mode. As a result, the fist microcontroller operation has
to be an access to ADF2 to program IOM-2 interface mode.
