Abstract: An error recovery method for a display system interface includes configuring a physical layer circuit in the display system interface for a high-speed mode of communication, causing the physical layer circuit to transmit display data over a serial bus while the physical layer circuit is configured for the high-speed mode of communication, halting transmission of the display data when an error indication signal transitions to an active state, configuring the physical layer circuit for a low-power mode of communication after terminating the transmission of the display data, reconfiguring the physical layer circuit for the high-speed mode of communication when the error indication signal transitions to an inactive state, and causing the physical layer circuit to resume the transmission of the display data after reconfiguring the physical layer circuit for the high-speed mode of communication.
