B.9.3 Exceptions/Trapping

A debug exception causes the processor to re-direct execution to a debug event handling routine.

The Intel® 80200 processor debug architecture defines the following debug exceptions:

•instruction breakpoint

•data breakpoint

•software breakpoint

•external debug break

•exception vector trap

•trace-buffer full break

When a debug exception occurs, the processor actions depend on whether the debug unit is configured for Halt mode or Monitor mode.
