4-18 Configuring the Emulator
For further information on mapping, refer to the examples in earlier
chapters of this manual and to the HP 64700 Terminal Interface User's
Reference manual.
The bc command lets you configure the emulator's response to various
emulation system and external events.
Write to ROM
If you want the emulator to break into the emulation monitor whenever
the user program attempts to write to a memory region mapped as
ROM, enter:
M> bc -e rom
You can disable this function by entering:
M> bc -d rom
When disabled, the emulator will not break to the monitor upon a write
to ROM.
If emualator writes to the memory mapped as ROM or guarded area in
internal DMA cycles, the emulator will not break to the monitor
regardless of this configuration.
Software Breakpoints
The bp command allows you to insert software traps in your code
which will cause a break to the emulation monitor when encountered
during program execution. If you want to enable the insertion and use
of software breakpoints by the bp command, enter:
M> bc -e bp
To disable use of software breakpoints, type:
M> bc -d bp
Any breakpoints which previously existed in memory are disabled, but
are not removed from the breakpoint table.
