dsPIC33FJ32MC202/204 and dsPIC33FJ16MC304
4.0
MEMORY ORGANIZATION
The dsPIC33FJ32MC202/204 and dsPIC33FJ16MC304
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
dsPIC33FJ32MC202/204 and dsPIC33FJ16MC304
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
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 for the dsPIC33FJ32MC202/204
and dsPIC33FJ16MC304 devices are shown in
