2.1.2.2 28F400BL-T Memory Map
The 28F400BL-T device has the 16-Kbyte boot
block located from 3E000H to 3FFFFH to accommo-
date those microprocessors that boot from the top
of the address map. In the 28F400BX-T the first
8-Kbyte parameter block resides in memory space
from 3D000H to 3DFFFH. The second 8-Kbyte pa-
rameter block resides in memory space from
3C000H to 3CFFFH. The 96-Kbyte main block re-
sides in memory space from 30000H to 3BFFFH.
The three 128-Kbyte main blocks reside in memory
space from 20000H to 2FFFFH, 10000H to 1FFFFH
and 00000H to 0FFFFH as shown in Figure 8.
