4.0 MEMORY ORGANIZATION
Note:
This data sheet summarizes the features
of the dsPIC33EPXXX(GP/MC/MU)806/
810/814 and PIC24EPXXX(GP/GU)810/
814 families of devices. It is not intended
to be a comprehensive reference source.
To complement the information in this data
sheet, refer to Section 4. “Program
Memory” (DS70613) of the “dsPIC33E/
PIC24E Family Reference Manual”, which
is available from the Microchip web site
(www.microchip.com).
The device architecture features separate program and
data memory spaces and buses. This architecture also
allows the direct access of program memory from the
data space during code execution.
4.1 Program Address Space
The device program address memory space is 4M
instructions. The space is addressable by a 24-bit
value derived either from the 23-bit PC during program
execution, or from table operation or data space
remapping as described in Section 4.8 “Interfacing
Program and Data Memory Spaces”.
User application access to the program memory space
is restricted to the lower half of the address range
(0x000000 to 0x7FFFFF). The exception is the use of
TBLRD/TBLWT operations, which use TBLPAG<7> to
permit access to the Configuration bits and Device ID
sections of the configuration memory space.
The device program memory map is shown in
Figure 4-1.
