PIC18(L)F2XK22/4XK22
For PIC18(L)FX4K22 devices, the code memory space
extends from 000000h to 003FFFh (16 Kbytes) in two
4-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.
