The
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.

3.1
The
PIC24HJ12GP201/202 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 3.4 “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 map for the PIC24HJ12GP201/202 device is
shown in Figure 3-1.
