Mapping Memory
The attributes can be:

Dual-port emulation memory.
One emulation memory range, up to 4 Kbytes in length, can be
given the dp attribute. The dp attribute specifies that the range
be mapped to the 4 Kbyte block of dual-port emulation
memory. If a foreground monitor program is selected, the dp
attribute is automatically assigned to the memory range
reserved for the monitor program.
Interlock emulation memory and target system /DSACK.
The dsi attribute specifies that accesses in that range of
emulation memory be synchronized with the target system.
This means the termination of accesses in the range will not
occur until the target system provides a /DSACK. If the target
system does not generate a /DSACK, the emulator will be
unable to break into the monitor and a "CPU in wait state"
status will result.
When interlocking is disabled, accesses to emulation memory
will be terminated by a /DSACK signal generated by the
emulator. Any cycle termination signals generated by the target
system during emulation memory accesses, including /BERR,
will be ignored.
Use 68340 chip select 0.
The cs0 attribute allows you to emulate the 68340's global chip
select operation. One memory range, either target or emulation,
can be given this attribute. Refer to the "To emulate global chip
select operation" task description at the end of this section.
