Multiple Datapointers
As a functional enhancement to the standard 8051 architecture, the C515C contains
eight 16-bit datapointers instead of only one datapointer. The instruction set uses just
one of these datapointers at a time. The selection of the actual datapointer is done in the
special function register DPSEL. Figure 8 illustrates the datapointer addressing
mechanism.
