3.0
For the PIC18F14K22/LF14K22 device, the code
memory space extends from 0000h to 03FFFh
(16 Kbytes)
PIC18F13K22/LF13K22 device, the code memory
space extends from 0000h to 01FFFh (8 Kbytes) in two
4-Kbyte blocks.
For the PIC18F14K22/LF14K22 addresses 0000h
through 0FFFh, however, define a “Boot Block” region
that is treated separately from Block 0. For the
PIC18F13K22/LF13K22 addresses 0000h through
07FFh, define the “Boot Block” region. All of these
blocks define code protection boundaries within the
code memory space. The size of the Boot Block in the
PIC18F14K22/LF14K22 devices can be configured as
2K, or 4 Kbyte (see Figure 3-1). The size of the Boot

MEMORY SIZE/DEVICE
(PIC18F14K22)
Block in the PIC18F13K22/LF13K22 devices can be
configured as 1K, or 2 Kbytes (see Figure 3-1). This is
done through the BBSIZ bit in the Configuration regis-
ter, CONFIG4L. It is important to note that increasing
the size of the Boot Block decreases the size of the
Block 0.
