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.
