For PIC18FX4K20 devices, the code memory space
extends from 000000h to 003FFFh (16 Kbytes) in two
8-Kbyte blocks. Addresses 000000h through 0007FFh,
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.
