Abstract
A system for controlling electronic apparatus, such as a television receiver, which employs a control circuit having a control program in a read only memory to sequentially communicate over an internal system bus in a predetermined interval with a plurality of controllable, operational circuit blocks forming the electronic apparatus, in which the control circuit selects a specific circuit block for data transfer upon a request signal. In one embodiment, a request signal is transmitted prior to a vertical blanking interval in a television signal and in another embodiment, a dedicated line is provided from a selected controllable unit to the control unit, whereby the request signal can be transmitted at any time, irrespective of whether data is being transferred at such time.
