MEMORY ORGANIZATION
The dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/
X04, and dsPIC33FJ128GPX02/X04 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 program address memory space of the
dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/X04,
and
dsPIC33FJ128GPX02/X04
devices
is
4M
instructions. 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 4.8
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 map for the dsPIC33FJ32GP302/304,
dsPIC33FJ64GPX02/X04, and dsPIC33FJ128GPX02/
X04 devices is shown in Figure 4-1.
