5.1
5.1.1
Exception handling is processing handled by a special routine, separate from normal program
processing, that is executed by the CPU in case of abnormal events. 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
flow to an exception handling routine, etc., is given the generic name of exception handling.
SH-4 exception handling is of three kinds: for resets, general exceptions, and interrupts.
5.1.2
The registers used in exception handling are shown in table 5.1.
