Exception Vectors
The exception vector parameter < vector> is a value between 0 and 255 that
acts as an index to the exception vector table. You are responsible for
providing the values for the table, i.e., the addresses of the interrupt routines.
If an exception vector is not given, the Interrupt Autovector for the specified
interrupt level is used.
Once/Repetitive Qualifiers
The Once qualifier sets a one-time interrupt. The Repetitive qualifier causes
the interrupt command to repeat. If you specify Repetitive, the debugger
repeats the same interrupt command after the interrupt occurs. The interrupt
command can be canceled with the Program Interrupt Remove command. The
Repetitive qualifier does not always force a debugger/simulator interrupt to
occur every < cycle_count> cycles because the interrupt can be delayed by
masking or by long instructions.

Examples
To set a one-time interrupt to occur in ten cycles at interrupt level 7 through
interrupt vector 66:
Program Interrupt Add Once 10,7,66
To set a repetitive interrupt occurring every 70000 cycles at interrupt level 7 to
interrupt vector 64:
Program Interrupt Add Repetitive 70000,7,64
To set a one-time interrupt to occur when program execution resumes at level
7 through autovector 7 (interrupt vector 31):
Program Interrupt Add Once 0,7
