摘要： A microcomputer includes a CPU capable of performing a plurality of tasks in a parallel time-sharing operation. The tasks include at least one special task having a fixed loop program with a constant increase of an instruction address. When the CPU performs a conditional judgement instruction in the special task, the CPU prohibits reflecting an execution result of the conditional judgement instruction to both of the CPU and a periphery circuit in a case where it is no need to perform an instruction described in the special task after the conditional judgement instruction.

摘要： A signal processing apparatus for processing a periodic signal outputted from a signal source has a central processing unit and a task switch timer. The central processing unit performs multiple tasks including a signal processing task in parallel. In the signal processing task, the central processing unit starts to process the periodic signal after performing a synchronization processing to synchronize with the periodic signal, setting the task switch timer to a predetermined time upon completion of the synchronization processing, and enabling an interrupt to the central processing unit upon completion of the synchronization processing. The task switch timer disables the interrupt to the central processing unit immediately before expiring. The task switch timer outputs a task switch signal to the central processing unit when expiring, so that the central processing unit switches to the signal processing task.

摘要： A microcomputer includes a plurality of operation mode selecting terminals to which data for selecting plural operation modes are set. The plurality of operation mode selecting terminals is designed so as to be usable as general-purpose input terminals or output terminals. A decoder decodes the data set to the plurality of operation mode selecting terminals and outputting a mode signal for switching an internal function in accordance with a selected operation mode. A timing signal output unit outputs to the decoder a timing signal for making the decoder execute a decode operation. The timing signal output unit outputs the timing signal when at least one of power-on-reset and an externally controlled reset is varied from an active state to an inactive state.

In the test mode, test instruction data is capable of being inputted from an external circuit.

摘要： During software development, a multichip module is used which encloses a target chip and a development chip in one package. A CPU of the development chip fetches instructions from a flash memory in the chip to execute them, and accesses RAM and peripheral circuits in the chip. For motor control circuits that exist only in the target chip, the CPU accesses them via serial communication. When the one-chip microcomputer operates alone, its CPU switches a switching circuit to a JTAG interface side to actuate a motor control circuit via internal serial communication.
