Advance Information

For PIC18FX6K20 devices, the code memory space

extends from 000000h to 00FFFFh (64 Kbytes) in four

16-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.
