2.3 Memory Maps
For PIC18FX6X0 devices, the code memory space extends from 0000h to 0FFFFh (64 Kbytes) in four 16-Kbyte blocks.
For PIC18FX5X5 devices, the code memory space extends from 0000h to 0BFFFFh (48 Kbytes) in three 16-Kbyte
blocks. Addresses, 0000h through 07FFh, 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 PIC18F2585/2680/4585/4680 devices can be configured as 1, 2 or 4K words (see
Figure 2-6). This is done through the BBSIZ<1:0> bits in the Configuration register, CONFIG4L. It is important to note
that increasing the size of the Boot Block decreases the size of Block 0.
