2.3
The code memory space extends from 0000h to 7FFFh
(32 Kbytes) in four, 8-Kbyte panels. Addresses 0000h
through 01FFh, however, define a “Boot Block” region
that is treated separately from Panel 1. All code
memory is on-chip.
In addition to the code memory space, there are three
blocks in the configuration and ID space that are acces-
sible to the user through Table Reads and Table Writes.
Their locations in the memory map are shown in
Figure 2-3.
