To Enable/Disable Breaks On Writes To Rom; To Include/Exclude Background States In The Trace - HP 64767 User Manual

breaks; answer "no" to disable breaks.

To include/exclude background states in the trace

• Answer "background" or "both" to the "Trace background or foreground
operation?" question to include background states in the trace; answer "foreground"
to exclude background states from the trace.
Answering "background" specifies that the analyzer trace only background cycles.
This is rarely a useful setting for user program debugging.
Answering "both" specifies that the analyzer trace both foreground and background
cycles. You may wish to specify this option so that all emulation processor cycles
may be viewed in the trace display.
Answering "foreground" specifies that the analyzer trace only foreground cycles.

The emulator will break into the emulation monitor whenever the user program
attempts to write to a memory region mapped as ROM.
Even though execution breaks into the monitor, the memory location is
modified if it's in emulation ROM or target system RAM mapped as ROM.
The emulator will not break to the monitor upon a write to ROM.
