The major operational modes are determined by the FM[2:0] framer mode bits, as well as a few other control bits.
Unused features are powered down and the data paths are held in reset. The configuration registers of the unused
features can be written to and read from. Some of the IO pins change functions in different operational modes. The
line interface operational modes are determined by the LM[2:0] bits.
