PIC18F87K22 FAMILY
28.6
The user program memory is divided into four blocks
for the PIC18FX5K22 and PIC18FX6K22 devices and
eight blocks for PIC18FX7K22 devices. One of these is
a boot block of 1 or 2 Kbytes. The remainder of the
memory is divided into blocks on binary boundaries.

locations of the bits are summarized in Table 28-4.
Each of the blocks has three code protection bits
associated with them. They are:
• Code-Protect bit (CPx)
• Write-Protect bit (WRTx)
• External Block Table Read bit (EBTRx)
