PIC18F2XXX/4XXX FAMILY
For PIC18FX5X0/X5X3 devices, the code memory
space extends from 000000h to 007FFFh (32 Kbytes)
in four 8-Kbyte blocks. For PIC18FX4X5/X4X8
devices, the code memory space extends from
000000h to 005FFFh (24 Kbytes) in three 8-Kbyte
blocks.
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.
