Memory Maps

For the PIC18FX3K20 devices, the code memory

space extends from 0000h to 01FFFh (8 Kbytes) in two

4-Kbyte blocks. Addresses 0000h through 01FFh,

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.
