DESCRIPTION:
For debugging. Causes the controller to pause execution of the given thread at the the given program line
number (which is not executed). All other threads continue running. Only one breakpoint may be armed at
any time. After a breakpoint is encountered a new breakpoint can be armed (to continue execution to the
new breakpoint) or BK will resume program execution. The
command can be used to
single step from the breakpoint. The breakpoint can be armed before or during thread execution.
