The overall structure of the code protection on the
PIC18 Flash devices differs significantly from other
PICmicro
divided on binary boundaries into individual blocks,
each of which has three separate code protection bits
associated with it:
• Code-Protect bit (CPn)
• Write-Protect bit (WRTn)
• External Block Table Read bit (EBTRn)
The code protection bits are located in Configuration
Registers 5L through 7H. Their locations within the
registers are summarized in Table 23-3.

XT, HS or LP Oscillator mode assumed.
GIE = 1 assumed. In this case, after wake-up, the processor jumps to the interrupt routine. If GIE = 0, execution will continue in-line.

In the PIC18FXX20 family, the block size varies with
the size of the user program memory. For PIC18FX520
devices, program memory is divided into four blocks of
8 Kbytes each. The first block is further divided into a
boot block of 2 Kbytes and a second block (Block 0) of
6 Kbytes, for a total of five blocks. The organization of
the blocks and their associated code protection bits are
shown in Figure 23-3.
For PIC18FX620 and PIC18FX720 devices, program
memory is divided into blocks of 16 Kbytes. The first
block is further divided into a boot block of 512 bytes
and a second block (Block 0) of 15.5 Kbytes, for a total
of nine blocks. This produces five blocks for 64-Kbyte
devices and nine for 128-Kbyte devices. The organiza-
tion of the blocks and their associated code protection
bits are shown in Figure 23-4.
