Abstract
A slave device may receive a clock signal from a master device via a bus. The slave device may detect a first pulse of the clock signal. The first pulse indicates that a bit is to be written to a slave shift register of the slave device. The slave device may identify a timeout threshold associated with the clock signal. The slave device may determine that the timeout threshold expired without a second pulse from the clock signal being detected. The slave device may reset, based on the timeout threshold expiring, the slave shift register to synchronize the slave shift register with a master shift register of the master device.
