dsPIC33F/PIC24H PROGRAMMING SPECIFICATION
gramming and the debug executive is used for in-circuit
debugging. This region of memory can not be used to
store user code.
2.4
Memory Map
The program memory map extends from 0x0 to
0xFFFFFE. Code storage is located at the base of the
memory map and supports up to 88K instructions
(about 256 Kbytes). Table 2-2 shows the program
memory size and number of erase and program blocks
present in each device variant. Each erase block, or
page, contains 512 instructions and each program
block, or row, contains 64 instructions.
Locations 0xF80000 through 0xF80017 are reserved
for the device Configuration registers.
Locations 0xFF0000 and 0xFF0002 are reserved for
the Device ID Word registers. These bits can be used
by the programmer to identify what device type is being
programmed. They are described in Section 7.0
“Device ID”. The Device ID registers read out
normally, even after code protection is applied.
Locations 0x800000 through 0x800FFE are reserved
for executive code memory. This region stores the
programming executive and the debugging executive.
The programming executive is used for device pro-
Figure 2-3 shows the memory map for the dsPIC33F/
PIC24H family variants.
