4.2.5
The
PIC24FJ256DA210
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
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, the upper half of data space. The
entire extended data space is organized into EDS

EXTENDED DATA SPACE (EDS)
Available only in PIC24FJXXXDA2XX devices. In the PIC24FJXXXDA110 devices, this space can be used to access external
memory using EPMP.
Available only in PIC24FJXXXDAX10 devices (100-pin).

pages, each having 32 Kbytes of data. Mapping of the
EDS page into the EDS window is done using the Data
Space Read register (DSRPAG<9:0>) for read opera-
tions and Data Space Write register (DSWPAG<8:0>)
for write operations. Figure 4-4 displays the entire EDS
space.
