METHOD AND APPARATUS FOR SELECTIVELY TERMINATING SIGNALS ON A BIDIRECTIONAL BUS BASED ON BUS SPEED |
摘要 |
A method of controlling signal termination includes providing first logic for selectively terminating signals received at a first device on a bidirectional data bus, providing second logic for selectively terminating signals received at a second device on the bidirectional data bus, sending first signals from the first device to the second device on the bidirectional data bus at a first speed, stopping the sending of the first signals, after stopping the sending of the first signals, enabling the second logic and shifting a reference voltage of the second device from a first level to a second level, after enabling the second logic at the second device, sending second signals from the first device to the second device on the bidirectional data bus at a higher speed, and controlling the first logic based on a speed of signals received at the first device on the bidirectional data bus. |
