Fatal Exceptions

The Target Configuration Module defines the processor exceptions which are to be

serviced by AMX and treated as fatal. These exceptions are specified by you b y

checking the appropriate boxes in the Fatal Exception window. The layout of the

window is shown below.

This example allows AMX to service the bus error, address error, privilege violation,

format error, uninitialized interrupt and spurious interrupt exceptions as fatal exceptions.

Note that the BOUNDS, CHK and TRAPV exceptions are also serviced by AMX in order to

allow the use of Task Trap Handlers by your application tasks. If any of these exceptions

occur outside a task or in a task with no Task Trap Handler, AMX will treat the exception

as fatal.

This example leaves the illegal instruction, trace and line emulation exceptions free for

use by a debugger. It also leaves the floating point exceptions free for use by a software

emulation library.
