Chapter 3: Loading and Executing Programs
Using Simulated Interrupts
Using Simulated Interrupts
The debugger can simulate program interrupts to your target program. The
debugger lets you specify a delay between interrupts in terms of a clock cycle
count. The pseudoregister @cycles maintains the current clock cycle count.
Caution
The pseudoregister @cycles is not implemented in the emulation
environment. Macros written for execution in both the simulation and
emulation environments must not refer to @cycles.
This section shows you how to:
•
•
To define simulated interrupts
• Using the command line, enter:
Program Interrupt Add
Select Repetitive or Once, specify how often the interrupt should occur,
specify the interrupt level number and exception vector number; then, press
the < Return> key.
Use the Program Interrupt Add command to cause a simulated program
interrupt to occur after a specified number of clock cycles have been executed.
You can define simulated interrupts to be repetitive or to occur only once.
