2.8.1
An SPI instruction allows a maximum address space of 8 bit. The address space for
supporting more than one configuration set is exceeding this 8 bit address room.
Therefore a page switch is introduced, which can be applied via register SFRPAGE (see
Figure

2.8.2
The register list is attached in the Appendix at the end of the document.
Registers for Configuration B are equivalent and not shown in detail.
All registers with prefix “A_” are related to Configuration A. All these registers are also
available for Configuration B having the prefix “B_”.
