2.3
The code memory space extends from 0000h to
0FFFFh
Addresses 0000h through 07FFh, 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.
