ABSTRACT:
When transfer condition information is set and the start of automatic control transfer is instructed, a transfer controller (host controller) automatically issues a setup stage transaction and automatically transfers a setup stage packet, then, if there is data to be transferred, it automatically issues a data stage transaction and automatically transfers a data stage packet. It then automatically issues a status stage transaction and automatically transfers a status stage packet. Device request data, the total size of transfer data, data stage present/absent information, transfer direction in the data stage, and maximum packet size are set in transfer condition registers. A pipe region is allocated in the packet buffer during host operation of USB On-The-Go.
