Chapter 10: Configuring the Emulator
Emulator Configuration Items
3 Read Specifier questions. If you answered yes to the periodic read question,
answer the next two questions:
Address for read cycles?
Enter a hexadecimal address from 0 to 0ffffffffH.
Function code for read cycles?
Select a function code from the softkeys.
Whenever it is executing, the background monitor will periodically read a byte
from the location you specify with your answer to the above two questions.
4 Monitor Filename question. If you selected the background monitor, skip to
question 6. If you selected the user_foregound monitor type, you need to
answer this question:
Monitor filename?
Specify the name of the absolute file containing your custom foreground
monitor code (such as, myforeground).
5 Interrupt Priority question. If you selected the foreground or
user_foreground monitor type, you need to answer the question:
Interrupt priority level for default foreground
monitor?
or
Interrupt priority level for user foreground monitor?
Enter a number from 0 to 7 in answer to the above question. Set the interrupt
priority level low enough to allow your target system to function correctly, yet
high enough to avoid excessive interrupt processing.
The emulator uses a level 7, non-maskable interrupt to interrupt the target
system and break into the monitor. When the foreground monitor is not
executing critical code (such as monitor entry and exit), the foreground
monitor will set the interrupt priority mask to the value given as an answer to
304
