Interrupt generator with synchronization function

This application relates to an interrupt generation device with synchronization function. By using one of the interrupt generation modules as a reference interrupt module, when the synchronization signal output by the synchronization output module arrives, the reference timing module adjusts the count of each interrupt module according to the synchronization signal, the reference count of the reference interrupt module, and the timing duration of the reference timing module itself, so as to change the output time of each subsequent interrupt signal.
