PIC18F2455/2550/4455/4550
25.5
The overall structure of the code protection on the
PIC18 Flash devices differs significantly from other
PICmicro
The user program memory is divided into five blocks.
One of these is a boot block of 2 Kbytes. The remainder
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 25-5 shows the program memory organization
for 24 and 32-Kbyte devices and the specific code pro-
tection bit associated with each block. The actual
locations of the bits are summarized in Table 25-3.
