Abstract

PURPOSE:To improve the accuracy of a timer without the deterioration of logical operation speed by dividing an operation part into 2 blocks for logical operation and timer processing to execute both the processing simultaneously and independently in parallel. CONSTITUTION:An operation part is divided into 2 blocks for logical operation and timer processing. On the basis of the operation codes of a program memory 3, a logical operation part 1 sends operation commands to an I/O interface 4, an internal output memory 5, a logical calculation time-up storing memory 6, and a timer starting status storing memory 7 which are selected through a memory data bus 8. A standard clock is inputted from a standard clock circuit 12 to a timer operation part 14, which outputs a logical operation part stopping signal 18 accompanied with the detection of the leading edge of the standard clock to stop the operation of the logical operation part 1. Subsequently the timer operation part 14 sends operation commands to an elapsed value storing memory 13, a timer operation time-up storing memory 15 and a timer starting status storing memory 16.
