Abstract
There is disclosed, for use in a data processing device containing a master processor and a slave processor, a mode selection circuit capable of selecting the operating mode of the slave processor. The mode selection circuit comprises a mode determination circuit capable of determining the current operating mode of the master processor and a mode control circuit capable of causing the slave processor to operate in a selected operating mode in response to the current operating mode of the master processor. The mode selection circuit causes the slave processor to boot up to a test program stored in a ROM coupled to the slave processor whenever the master processor is in a test mode. If the master processor is in a system application mode, the mode selection circuit causes the slave processor to execute a system application program stored in a RAM coupled to the slave processor.
