Chapter 4:Connecting the Emulator to a Target System
Installing Emulator Features
Resetting into the foreground monitor
If you have successfully established operation of the background monitor, or if you
have decided that you cannot use the background monitor because you require
interrupt servicing, then it is time to evaluate the foreground monitor. The first
thing to do is to enter the foreground monitor from reset. Perform the following
command sequence to enter the monitor.

1 Reset the emulator, and the target system if necessary, using whatever reset
procedure you determined to work.
2 Configure the emulator, as follows:
cf mon=fg
cf monaddr=addr as appropriate for the target system
map addr..addr+0fff eram <dstgt,ds32> as appropriate for the address
mapping
cf monintr=0
cf berr=en
cf xdma=en
cf ti=en
cf db=<32,16>, as appropriate for your target system
cf glbcs=<32,16,8>, as appropriate for your target system
3 Set up a trace to capture all MC68360 cycles. Background cycles do not need
to be traced to see foreground monitor operation.
tg any
tsto any
tck -u
t
4 Execute the command: rst -m
This tells the emulator to release reset, but enter the monitor.
5 Verify that the emulator is in the monitor.
The prompt should be "M>", indicating correct operation in the monitor.
There is not much that can go wrong up to this point since everything required
has been previously verified.
