2.3
The code memory space extends from 0000h to 3FFFh
(16 Kbytes) in four 4-Kbyte blocks. Addresses 0000h
through 01FFh, however, define a “Boot Block” region
that is treated separately from Block 0. All of these
blocks define code protection boundaries within the
code memory space.
In contrast, code memory panels are defined in 8-Kbyte
boundaries. Panels are discussed in greater detail in
Section 3.2.
