The problem to be met by the present invention is to provide a controller which can execute control processing in synchronism with a synchronizing signal output from a host controller without taking into consideration a difference between a clock signal used for generating a synchronizing signal of the host controller and a clock signal used for generating a control cycle signal of a controller; and can enhance accuracy performance of control. According to the present invention, in a controller having a control interrupt processing section, a synchronization interrupt processing section adjusts means for generating a control cycle signal to thus generate a control interrupt signal such that the control cycle signal is generated while being delayed by an amount equal to or greater than the duration of an accuracy error between a quartz oscillator used for generating a synchronization interrupt signal and a quartz oscillator used for generating the control cycle signal, thereby executing control interrupt processing in synchronism with the synchronizing signal from the outside.
