The Data Page Pointers DPP0, DPP1, DPP2, DPP3
These four non-bit addressable registers select up to four different data pages being
active simultaneously at run-time. The lower 10 bits of each DPP register select one of
the 1024 possible 16-Kbyte data pages while the upper 6 bits are reserved for future use.
The DPP registers allow access to the entire memory space in pages of 16 Kbytes each.
