For PIC18F2423/4423 devices, the code memory
space extends from 000000h to 003FFFh (16 Kbytes)
in two 8-Kbyte blocks. Addresses 000000h through
0003FFh, 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.
