Multiple Datapointers
As a functional enhancement to the standard 8051 architecture, the C509-L 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 regsiter DPSEL.
Figure 14
illustrates the datapointer addressing mechanism.
