PIC18F2220/2320/4220/4320
23.5
The overall structure of the code protection on the
PIC18 Flash devices differs significantly from other
PIC
The user program memory is divided into five blocks.
One of these is a boot block of 512 bytes. The remain-
der of the memory is divided into four blocks on binary
boundaries.

Each of the five blocks has three code protection bits
associated with them. They are:
• Code-Protect bit (CPn)
• Write-Protect bit (WRTn)
• External Block Table Read bit (EBTRn)
Figure 23-5 shows the program memory organization
for 4 and 8-Kbyte devices and the specific code protec-
tion bit associated with each block. The actual locations
of the bits are summarized in Table 23-3.
