• Description: High-performance, 16-bit Microcontrollers
• Manufacturer: Microchip Technology Inc.

3.0
The PIC24HJXXXGPX06/X08/X10 architecture fea-
tures 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
PIC24HJXXXGPX06/X08/X10 devices is 4M instructions.
The space is addressable by a 24-bit value derived from
either the 23-bit Program Counter (PC) during program
execution, or from table operation or data space remap-
ping as described in Section 3.4 “Interfacing Program
and Data Memory Spaces”.
User 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.
Memory maps for the PIC24HJXXXGPX06/X08/X10
family of devices are shown in Figure 3-1.
