28.6
The user program memory is divided into four blocks
for the PIC18FX5K90 device and PIC18FX6K90
devices, and eight blocks for PIC18FX7K90 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.

Each of the 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)
