摘要： When a first mode (with-SOF mode) has been set, data transfer is performed while SOF packets are transferred at frame periods, and when a second mode (non-SOF mode) has been set and also non-periodic (bulk) transfer is being performed, the periodic transfer of SOF packets is disabled and non-periodic data is transferred. If there is no non-periodic data to be transferred, a SOF packet is transferred in the frame period, even if the second mode has been set. During host operation with USB on-the-go (OTG), pipe regions are allocated to the packet buffer, and non-periodic data is transferred automatically to or from end points while the periodic transfer of SOF packets is disabled. When all of the automatic transfer instruction signals of the pipe regions are inactive, SOF packets are transferred periodically even if the second mode has been set.
摘要翻译：当已经设置了第一模式（具有SOF模式）时，在帧周期传送SOF分组时执行数据传送，并且当已经设置了第二模式（非SOF模式）并且还非非周期（大量）传送正在执行，SOF分组的周期性传输被禁用并且非周期性数据被传送。如果没有要传送的非周期性数据，即使已经设置了第二模式，也在帧周期中传送SOF数据包。在使用USB移动（OTG）的主机操作期间，管道区域被分配给分组缓冲器，并且在周期性地传送SOF分组被禁用时，非周期性数据被自动传送到端点或从端点传送。当管道区域的所有自动传送指令信号都不活动时，即使设置了第二模式，也会周期性地传送SOF数据包。

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.
