20110182216 | INTERFACE DEVICE, COMMUNICATIONS SYSTEM, NON-VOLATILE STORAGE DEVICE, COMMUNICATION MODE SWITCHING METHOD AND INTEGRATED CIRCUIT - An interrupt request cannot be transmitted while a data read command or a data write command transmitted from a host device to a slave device is being processed in a half-duplex mode. Disclosed are a host device and a slave device that are set to a full-duplex mode by temporarily switching the communication direction of a first transmission channel or a second transmission channel after completing transmission and reception of a predetermined number of data packets in the half-duplex mode. The host device or the slave device can thus transmit an interrupt request, such as a request associated with a wait status or a busy status, to its communication target using the temporary full-duplex mode. This enables the host device or the slave device to process such an interrupt request during high-speed data transfer performed in the half-duplex mode. | 07-28-2011 |

A peripheral device transmits an interrupt request to a host device using a signal line for a clock signal when the clock signal output has been stopped. The host device receives the interrupt request, and resumes outputting a clock signal to enable data transmission and reception to and from the peripheral device. This enables the peripheral device to transmit an interrupt request to the host device promptly when the output of the clock signal from the host device has been stopped. | 01-26-2012 |
