Getting Started and Debugger

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.
