CPU CONFIGURATION CONTROLLER Register/Multiplexer For Microprocessor VID

The Fairchild FM3565 replaces the PC motherboards CPU configuration switches with an electronic implementation, consist- ing of a 5-bit multiplexed port, standard 2-wire bus Interface and non-volatile Latches with external hardware control. The FM3565 multiplexes the I-port input signals with two internal non-volatile Registers that CAN be loaded through the serial port. The multiplexer output is under hardware control, and is deter- mined by the inputs OVRD, MUXSEL, and A/B. Pull-up resistors are provided on the input port to accommodate connections to open drain outputs and to eliminate the need for external resistors. The device has open-drain outputs for easy Interface to devices with different VDD Levels. By Fairchild Semiconductor
