PURPOSE:To reduce a burden of preparation of a program by providing a central processing circuit processing a signal, a register storing data on an initial value, a memory storing data on a waveform, a means of specifying an address of the waveform data, a signal processing means of outputting the signal, and a means of switching a data bus. CONSTITUTION:An address of ROM 28 is specified based on data on an initial value. Then, data Da, Db and Dc on a waveform of the aforesaid address are read out. A signal processing means 36 applies a signal processing to the waveform data Da, Db and Dc and outputs the results. Next, a count operation is executed when a signal led out to a multiplexer 27 coincides with the address data and when a theoretical value of a fourth bit of a register CONT is zero. When a count value of a register CNT 12 is a prescribed value, thereafter, an interrupt is generated and a desired value can be set in the register CNT 12. When a count value of a register CNTFF is a prescribed value or above, an interrupt signal is generated. |
