Abstract: A method for handling configuration data for an interconnection protocol within hibernation operation, a controller and an electronic device are provided. The method includes the following steps. In an electronic device, a hibernation entering indication signal indicating entering a hibernation state of the interconnection protocol is received. The electronic device has a memory and an index table, wherein the index table includes attribute identifiers corresponding to management information base (MIB) attributes, which belong to sub-layers of a link layer of the interconnection protocol and are required to be retained during hibernation. In response to the hibernation entering indication signal, MIB attribute storing is performed by a hardware protocol engine for implementing the link layer to read, for each one of the sub-layers, attribute data from the sub-layers according to the attribute identifiers from the index table sequentially and to write the attribute data sequentially to the memory.

Abstract: A controller capable of preparing capability information for an interconnection protocol and an electronic device are provided. The controller is for a first device linkable to a second device according to the interconnection protocol. The controller includes a hardware protocol engine and a processing unit. The hardware protocol engine is for implementing a link layer of the interconnection protocol, and capable of performing capability extraction and frame formatting to output capability frame information to a data buffer region and capable of sending, according to content of the data buffer region, a capability frame to the second device during Link Startup Sequence (LSS) capability exchange for the interconnection protocol. The processing unit is configured to be capable of modifying, during the LSS capability exchange, the content of the data buffer region after the capability frame information is output to the data buffer region and before the capability frame is sent to the second device.
