2.3 Memory Maps
For PIC18(L)FX3K22 devices, the code memory space
extends from 000000h to 001FFFh (8 Kbytes) in two 4-
Kbyte blocks. Addresses 000000h through 0001FFh,
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.
