PIC18(L)F2X/4XK50

For PIC18(L)FX5K50 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.
