2.3
For the PIC18FX3K20 devices, the code memory
space extends from 0000h to 01FFFh (8 Kbytes) in two
4-Kbyte blocks. Addresses 0000h through 01FFh,
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.
