Section 5 Exception Handling
5.1
Summary of Exception Handling
Exception handling processing is handled by a special routine which is executed by a reset,
general exception handling, or interrupt. For example, if the executing instruction ends
abnormally, appropriate action must be taken in order to return to the original program sequence,
or report the abnormality before terminating the processing. The process of generating an
exception handling request in response to abnormal termination, and passing control to a user-
written exception handling routine, in order to support such functions, is given the generic name of
exception handling.
The exception handling in this LSI is of three kinds: resets, general exceptions, and interrupts.
