Line 18: This line maps memory addresses from 0x0d000 to 0xdffff as reserved. Most
memory space in this region is unused, protected (E86MON utility), or non-existant on
the SD186EM board. Paradigm Debug/RT will catch the error if an application program
attempts to access the addresses defined as reserved.
Line 19: This line defines the PDREM and E86MON memory regions as read-only. As
defined in the
pdrem.cfg
file, PDREM starts at address 0xe0000.
Figure 8 -
sieve.cfg
File for SD186EM Board
Lines 21 to 23 are commented out because the chip select registers have been set by the
E86MON utility.
