Abstract

Disclosed is an interface (10, 40) between a master device (30) and a slave device (20). The interface includes a bit serial bidirectional signal line (10A) for conveying commands and associated data from the master device to the slave device, and for conveying a reset signal, an interrupt signal, and a learning sequence signal for specifying a duration of a bit time for data transferred from the slave device to the master device. The bit serial bidirectional signal line further indicates an accessory device connected/disconnected state to the master device.
