Zusammenfassung:The present disclosure is generally directed to a method and apparatus to communicate data between two or more semiconductor devices. In an embodiment, a method includes synchronizing a master device with a slave device, where the master device includes a semiconductor device. Synchronizing includes transmitting a first synchronization marker data pattern via a first serial interface from the master device at a first time, and receiving a second synchronization marker data pattern via a second serial interface at the master device at a second time in response to transmitting the first synchronization marker data pattern. Synchronizing also includes determining, based at least in part on the first time and the second time, a third time when a reply is to be received by the master device in response to a request transmitted from the master device to the slave device.
