ABSTRACT:
A video display with data bus control has a standby and an operate condition. The video display comprises a microprocessor having a bi-directional data bus and is selectably operable in one of the operate and standby modes. A power supply is controllably coupled to the microprocessor for supplying power in one of the operate and the standby modes. An integrated circuit is coupled to the power supply and has bi-directional data bus control capability. A coupling device is responsive to the power supply and couples the bi-directional data bus to the integrated circuit in response to the operate mode and isolates the bi-directional data bus in response to the standby mode.
