BUS TIE-DOWN WITHOUT PULL-UP RESISTORS

摘要

A circuit for tying down a computer bus when the bus is idle by monitoring a series of signals which indicate whether the bus is being used and storing the data signal values on the bus, such that when the bus goes idle the last data value on the bus immediately prior to the bus becoming idle is applied to the bus to hold it at its last known signal value. When a new bus operation is initiated the bus is automatically released for normal operation.
