Genius I/O Block Configuration Parameters

When using the GHS Control Strategy, if a Genius Bus Controller is set to redundant, then all of its I/O blocks must also be set to redundant.

When using the GDB Control Strategy, if a Genius Bus Controller is set to redundant, then all of its TI/O blocks are normally configured as redundant.

If a Genius Bus Controller is set to non-redundant, all of its I/O blocks must also be set to non- redundant.
