2.3 Memory Map
The code memory space extends from 0000h to
1FFFFh (128 Kbytes) in eight 16-Kbyte blocks.
Addresses 0000h through 01FFh, however, define a
“Boot Block” region that is treated separately from
Block 1. 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.
