A data transfer control device includes an ATA device-side I/F which transfers data between the data transfer control device and an ATA host through a bus ATABUS, an ATA host-side I/F which transfers data between the data transfer control device and an ATA device through a bus ATABUS, a first interface which transfers data through a first bus, and a transfer controller which controls data transfer among the device-side I/F, the host-side I/F, and the first interface.

Data transfer control device and electronic instrument

A transfer controller (or a host controller) issues IN tokens to a plurality of USB devices connected to USB and including first and second USB devices. When data including destination information which specifies the second USB device as a destination has been received in response to an IN token issued to the first USB device, the transfer controller issues an OUT token to the second USB device and transmits the received data from the first USB device to the second USB device. The transfer controller issues an IN token to at least one of the USB devices which has declared itself to be a local area network (LAN) node.

USB data transfer control device including first and second USB device wherein destination information about second device is sent by first device

A semiconductor device which has an internal circuit for performing a circuit operation corresponding to a signal inputted or outputted through an input/output interface circuit adapted to a serial bus. The semiconductor device has a non-volatile storage circuit for storing identification data. Internal identification data stored in the non-volatile storage circuit is compared with external identification data included in an input signal supplied through the serial bus by a comparator circuit. A control circuit is responsive to a match detecting signal generated by the comparator circuit to perform a circuit operation corresponding to an input signal subsequently supplied through the serial bus to change the internal identification data stored in the non-volatile storage circuit.
