4.0 MEMORY ORGANIZATION

Note:

This data sheet summarizes the features

of the dsPIC33FJ32GS406/606/608/610

and dsPIC33FJ64GS406/606/608/610

families of devices. It is not intended to be

a comprehensive reference source. To

complement the information in this data

sheet, refer to the dsPIC33F/PIC24H

Family Reference Manual, “Section 4.

Program Memory” (DS70203), which is

available from the Microchip web site

(www.microchip.com).

The

dsPIC33FJ32GS406/606/608/610

and

dsPIC33FJ64GS406/606/608/610 architecture fea-

tures separate program and data memory spaces and

buses. This architecture also allows the direct access

to program memory from the data space during code

execution.

4.1 Program Address Space

The program address memory space is 4M instruc-

tions. The space is addressable by a 24-bit value

derived either from the 23-bit Program Counter (PC)

during program execution, or from table operation or

data space remapping as described in Section 4.6

“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 memory maps are shown in Figure 4-1.
