3.8.2
DuSLIC incorporates signal generators and test features implemented to accomplish a
variety of diagnostic functions. The SLICOFI-2x device generates all test signals,
processes the information that comes back from the SLIC, and provides the data to a
higher level master device, such as a microprocessor. All the tests can be initiated by the
microprocessor and the results can be read back very easily.
