4.0
There are three memory blocks in Enhanced MCU
devices. These memory blocks are:
• Program Memory
• Data RAM
• Data EEPROM
Data and program memory use separate busses,
which allows for concurrent access of these blocks.
Additional detailed information for FLASH program
memory and Data EEPROM is provided in Section 5.0
and Section 6.0, respectively.
4.1
A 21-bit program counter is capable of addressing the
2-Mbyte program memory space. Accessing a location
between the physically implemented memory and the
top of the 2-MByte range will cause a read of all ‘0’s (a
NOP instruction).

The PIC18F2539 and PIC18F4539 each have a total of
24 Kbytes, or 12K of single word instructions of FLASH
memory, from addresses 0000h to 5FFFh. The next
8 Kbytes beyond this space (from 6000h to 7FFFh) are
reserved for the Motor Control kernel; accessing
locations in this range will return random information.
The PIC18F2439 and PIC18F4439 each have
12 Kbytes, or 6K of single word instructions of FLASH
memory, from addresses 0000h to 2FFFh. The next
4 Kbytes of this space (from 3000h to 3FFFh) are
reserved for the Motor Control kernel; accessing
locations in this range will return random information.
The RESET vector address for all devices is at 0000h,
and the interrupt vector addresses are at 0008h and
0018h.
The
PIC18FX539 devices are shown in Figure 4-1.
