PIC18(L)F2XK22/4XK22
For PIC18(L)FX6K22 devices, the code memory space
extends from 000000h to 00FFFFh (64 Kbytes) in four
16-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.
