Abstract
An interface circuit in a computing device may communicate with user-interface devices using shared slots during time intervals. In particular, the computing device may transmit outgoing messages to the user-interface devices at a first predefined time during sequential time intervals when the user-interface devices transition from a sleep mode to a normal mode. In response, the computing device may receive incoming messages from one or more of the user-interface devices at a second predefined time following the first predefined time during the sequential time intervals. Then, the computing device may transmit a multicast message to the user-interface devices at a third predefined time during the sequential time intervals. In response to the given multicast message, one of the user-interface devices may communicate data to the computing device. Note that, in some instances, a multicast time slot may instead be used to communicate data to one of the user-interface devices.
