Notes:

1. These are read only registers.

2. The meaning of the mains, generator and bus phase rotation codes is given in the table below.

3. Registers 95-123 have been added to support the 8680 although not all will be implemented initially.

4. Registers 180 to 192 added to allow mimics of either S1 or S2 load/watts/lead-lag registers according to which side is on load.
