PIC24FJ256GB210 FAMILY
4.2.5
The
PIC24FJ256GB210
accomplished by a new technique, called the Extended
Data Space (EDS).
The EDS includes any additional internal extended
data memory not accessible by the lower 32 Kbytes of
data address space, any external memory through
EPMP and the Program Space Visibility (PSV).
The extended data space is always accessed through
the EDS window, which is the upper half of data space.
The entire extended data space is organized into EDS

EDS page into the EDS window is done by using the
Data Space Read register (DSRPAG<9:0>) for read
operations
(DSWPAG<8:0>) for write operations. Figure 4-4
