Programmable controller has central processing unit for processing interrupt in response to interrupt request signal from pulse division stage to control output of pulse generation stage

摘要

The controller has a pulse generation stage for outputting a pulse sequence with a set period, a pulse division stage for dividing the pulse sequence with a predetermined ratio and outputting an interrupt request signal with a period greater than the pulse length period by an integral factor and a central processing unit for processing an interrupt in response to the interrupt request signal to control the output of the pulse generation stage. The controller has a pulse generation stage (2) for outputting a pulse sequence with a set period, a pulse division stage (3) for dividing the pulse sequence with a predetermined division ratio and for outputting an interrupt request signal with a period greater than the pulse length period by an integral factor and a central processing unit (1) for processing an interrupt in response to the interrupt request signal from the pulse division stage to control the output of the pulse generation stage.
