9-5. CPU Exceptional Error
The functions of the CPU (SH series) include exception handling. If an exception other than reset and
general interrupt (hereafter called “general exception”) occurs, the OS displays a message as shown
below and stops the operation of ECR, because the operation after that cannot be guaranteed.
The example shown below indicates the screen displayed when “reservation instruction code excep-
tion” occurs.
The values of error no., error point and access adrs vary according to errors.
