23.3
The overall structure of the code protection on the
PIC18 Flash devices differs significantly from other
PIC
The user program memory is divided into three or five
blocks, depending on the device. One of these is a
Boot Block of 0.5K or 2K bytes, depending on the
device. The remainder of the memory is divided into
individual blocks on binary boundaries.

Each of the blocks has three code protection bits asso-
ciated with them. They are:
• Code-Protect bit (CPn)
• Write-Protect bit (WRTn)
• External Block Table Read bit (EBTRn)
Figure 23-2 shows the program memory organization
for 8, 16 and 32-Kbyte devices and the specific code
protection bit associated with each block. The actual
locations of the bits are summarized in Table 23-3.
