Methods and apparatus for implementing a device side advanced serial protocol

摘要

A peripheral device having a protocol communication chip is provided. The protocol communication chip is configured to manage communication between the peripheral device and a host computer over a serial bus. The protocol communication chip includes a bus interface and a link control and status register. The link control status register is provided for setting link parameters, and is configured to be either read or written by the host computer by the transmission of a 16 byte packet having a DataType 0. The 16 byte packet is an OUTDATA packet for control and an INSTART packet for status. The peripheral device is configured to receive device command information from the host computer using a DataType 1 packet, and host computer being configured to access data resident on the peripheral devices using a DataType 2 packet.
