PIC18F2XK20/4XK20

For PIC18FX5K20 devices, the code memory space

extends from 000000h to 007FFFh (32 Kbytes) in four

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.
