Abstract
In some examples, an apparatus includes a circuit configured to receive communication on a first bus. The circuit is also configured to provide the communication on a second bus for a first period of time. The circuit is also configured to monitor a duration of the providing of the communication on the second bus. The circuit is also configured to, responsive to the duration exceeding a threshold amount, stop providing the communication on the second bus for a second period of time.
Claims12
An apparatus, comprising:
- a circuit that includes:
- repeater circuitry having first and second inputs and first and second outputs;
- a processing circuit having first and second outputs;
