To add memory map entries
•
Choose Map
→
Add New Entry from the pulldown menu in the memory map
window.
•
Press and hold the select mouse button and choose Add New Entry from the popup
menu.
•
Using the command line, enter the address range, memory type, and possibly an
emulator_terminates_bus_cycles, or transfer_cache_inhibit attribute, or both
attributes for each emulation memory range.
You can characterize memory ranges as emulation RAM, emulation ROM, target
system RAM, target system ROM, or as guarded memory.
Guarded memory accesses will cause emulator execution to break into the monitor
program.
Writes to locations characterized as ROM will cause emulator execution to break
into the monitor program if you choose "Yes" for the "Break processor on Write to
ROM" option in the "Emulator Configuration: General Items" dialog box.
RAM memory in the emulation or target system will be changed by processor
writes, even if that memory has been characterized as ROM.
You can include the transfer cache inhibit attribute with any memory range. If
included, no data will be loaded into either the instruction cache or data cache
during any transactions occuring in the associated memory range. This ensures that
all activity will appear on the emulation bus and be available for tracing with the
emulation-bus analyzer.
You can include the "Emulator Terminates Bus Cycles" attribute with any memory
range. If included, the emulator will terminate bus cycles without regard to the
state of the target system. This is useful in ranges where the TA, or TEA, or both
signals are not available from the target system. The danger of this option is that
the emulator may become out of sync with the target system if the target system
supplies these signals.
You can specify that a particular address range be loaded into the dual-port memory
if using of a background monitor in the Monitor Setup dialog box.
