For PIC18F2685/4685 devices, the code memory
space extends from 0000h to 017FFFh (96 Kbytes) in
five 16-Kbyte blocks. For PIC18F2682/4682 devices,
the code memory space extends from 0000h to
0013FFFh (80 Kbytes) in four 16-Kbyte blocks.
Addresses, 0000h through 0FFFh, however, define a
“Boot Block” region that is treated separately from
Block 0. All of these blocks define code protection
boundaries within the code memory space.
The size of the Boot Block in PIC18F2685/4685 and
PIC18F2682/4682 devices can be configured as 1, 2 or
4K words (see
