摘要： 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.

摘要： A signal state detection circuit of a data transfer control device notifies a processing of results detected by a line state detection circuit or a power supply line detection circuit by using an interrupt signal. The processing sets a state command corresponding to a state of a transition destination judged based on the notified detection results in a control register of a state controller. A state command decoder decodes the state command set in the control register and generates a control signal. A signal line control circuit controls a signal state of at least one of signal lines formed of data signal lines (D+ and D−) and power supply lines (VBUS and GND) based on the control signal.

摘要： A plurality of pipe regions PIPE0 to PIPEe in which data transferred to and from endpoints is stored are allocated in a packet buffer (FIFO). Transfer condition information on data transfer between the pipe regions and the endpoints is set in transfer condition registers TREG0 to TREGe in a register section. A host (transfer) controller automatically generates a transaction for each of the endpoints based on the transfer condition information (total size, maximum packet size, transfer direction, number of continuous execution times, token issue interval, and the like) set in the transfer condition registers, and automatically transfers data between each pipe region and the endpoint. An OTG (state) controller which controls a state of USB On-The-Go is provided. The pipe regions are allocated in the packet buffer during a host operation.

摘要： A transaction is automatically issued with respect to one of end points and data is automatically transferred while the remaining data size of the transfer data is calculated based on the total size and the maximum packet size. When the remaining data size in the current transaction is less than the maximum packet size, the next transaction is issued automatically, and a short packet is transferred automatically to nest one of the end points. When the payload size of the packet to be transferred by the current transaction is the maximum packet size and the remaining data size of the transfer data is zero, a short packet of zero data length is transferred automatically to the next one of the end points. When DMA transfer is complete and the remaining data to be transferred is zero, a short packet of zero data length is transferred automatically in response to an IN token from a host. Data transfer according to USB On-The-Go is performed.

A power supply switch circuit connects a power supply circuit with a VBUS line based on transition of the state controller. A power supply switching circuit of a power supply control circuit connects the VBUS line or the power supply circuit with the data transfer processing circuit based on a switching signal. The switching signal is generated based on an output signal of a switch circuit or a control signal from the state controller.
