Fig.8.12.1 Sequence at Detecting Software Runaway Detection
8.12 SOFTWARE RUNAWAY DETECT FUNCTION
This microcomputer has a function to decode undefined instructions
to detect a software runaway.
When an undefined op-code is input to the CPU as an instruction
code during operation, the following processing is done.
The CPU generates an undefined instruction decoding signal.
The device is internally reset due to the undefined instruction de-
coding signal.
As a result of internal reset, the same reset processing as in the
case of ordinary reset operation is done, and the program restarts
from the reset vector.
Note, however, that the software runaway detecting function cannot
be disabled.
