Abstract: A process for a slave device on a serial data bus to make an in-band interrupt request to a master device includes checking whether a backoff time stored by a backoff timer has expired. When the backoff time has not expired, the slave device refrains from initiating the in-band interrupt request to the master device in response to a start condition on the serial bus. However, when the backoff time has expired, the slave device is permitted to initiate the in-band interrupt request to the master device in response to the start condition on the serial bus.
