Notes:

1. These are read only registers.

2. Each auxiliary sender has a register describing it's type as shown in the table below.

3. Auxiliary sender values are always signed regardless of the category.

4. An unused auxiliary sender should return the appropriate unimplemented sentinel in both the category and value registers, however, some products may return a 0 value in the category register to indicate that it is unimplemented.

5. Registers 12-15 have been added to 55xx from version 9 upwards

6. Registers 16-17 have been added to 8xxx from version 2 upwards
