    • Aspects of the invention can provide a data transfer control device that can switchover VBUS feed voltage. The transfer controller can send a switchover request packet to switch over a VBUS feed voltage to a plug B coupling side (device B side). When the transfer controller receives a switchover consent packet, it can instruct a feed switch circuit to switch over from normal voltage feed to low voltage feed. Then, monitor of the VBUS normal voltage level can be stopped and monitor of the VBUS low voltage level is started. The transfer controller receives the switchover request packet to switch over the VBUS feed voltage from the plug A coupling side (device A side). If it agrees to the switchover, it can send the switchover consent packet. And then, the monitor of the VBUS normal voltage level can be stopped and the monitor of the VBUS low voltage level is started. The switchover request packet and the switchover consent packet can be sent by a control transfer.
    • 本发明的方面可以提供一种能够切换VBUS馈电电压的数据传输控制装置。 传输控制器可以发送切换请求包以将VBUS馈电电压切换到插头B耦合侧(设备B侧)。 当传输控制器收到切换同意信息包时,它可以指示馈电开关电路从正常电压馈送切换到低电压馈电。 然后,可以停止对VBUS正常电压电平的监视,并开始VBUS低电压电平的监视。 传输控制器接收切换请求包以从插头A耦合侧(设备A侧)切换VBUS馈电电压。 如果同意切换,则可以发送切换同意报文。 然后,可以停止VBUS正常电压电平的监视器,并开始VBUS低电平的监视。 可以通过控制转移发送切换请求报文和切换同意报文。

    • 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.
    • 在存储分组缓冲器(FIFO)的情况下分配存储了从端点传送的数据的多个管道区域PIPE 0〜PIPEe。 在管道区域和端点之间的数据传输的转移条件信息被设置在寄存器部分的传送条件寄存器TREG 0到TREGe中。 主机(传输)控制器根据转移中设置的传送条件信息(总大小,最大包大小,传送方向,连续执行次数,令牌发放间隔等)自动生成每个端点的事务。 条件寄存器,并在每个管道区域和端点之间自动传输数据。 提供控制USB On-The-Go状态的OTG(状态)控制器。 管道区域在主机操作期间被分配在分组缓冲器中。

    • A data transfer control device includes a PATA I/F connected to a PATA bus, an SATA I/F connected to an SATA bus, and a sequence controller that controls a transfer sequence. The PATA I/F includes a task file register (TFR). The sequence controller suspends transmission of a register FIS corresponding to an ATA packet command issued by a host to a device, and performs a dummy setting that causes the host to issue an ATAPI packet command using the TFR. The sequence controller transmits the register FIS corresponding to the ATA packet command to the device after the host has issued the ATAPI packet command.
    • 数据传输控制装置包括连接到PATA总线的PATA I / F,连接到SATA总线的SATA I / F以及控制传送顺序的序列控制器。 PATA I / F包括任务文件寄存器(TFR)。 序列控制器暂停将与由主机发出的ATA分组命令对应的寄存器FIS发送到设备,并执行使主机使用TFR发出ATAPI分组命令的虚拟设置。 序列控制器在主机发出ATAPI分组命令后,将与ATA分组命令对应的寄存器FIS发送给设备。
