The Background Monitor
On emulator power-up, or after initialization, the emulator uses the
background monitor program. The background monitor does not
occupy processor address space.
The Foreground Monitor
You can configure the emulator to use a foreground monitor program.
When a foreground monitor is selected it executes in the foreground
emulator mode. The foreground monitor occupies processor memory
space and executes as if it were part of your program.
Register Display and
You can display or modify the 7700 Series internal register contents.
This includes the ability to modify the program counter (PC) and the
Modification
program bank register (PG) values so you can control where the
emulator starts a program run.
Single-Step
When you are using the background monitor, you can direct the
emulation processor to execute a single instruction or a specified
number of instructions.
Breakpoints
You can set the emulator/analyzer interaction so the emulator will
break to the monitor program when the analyzer finds a specific state
or states, allowing you to perform post-mortem analysis of the program
execution. You can also set software breakpoints in your program.
This feature is realized by inserting BRK instructions into user
program. Refer to the "Using Software Breakpoints" section of
"Getting Started" chapter for more information.
Real Time Operation
Real-time signifies continuous execution of your program at full rated
processor speed without interference from the emulator. (Such
interference occurs when the emulator needs to break to the monitor to
perform an action you requested, such as displaying target system
memory.) Emulator features performed in real time include: running
and analyzer tracing. Emulator features not performed in real time
include: display or modify of target system memory; load/dump of
target memory, display or modification of registers, and single step.
