20120084378 | Communication system, master node, and slave node - A slave node communicably coupled to a master node via a bus determines determine whether an active communication mode or a passive communication mode is started based on a header transmitted from the master node. The slave node transmits the header and an ID subsequent to the header when it is determined that the active communication mode is started based on the received header. The ID requests active transmission of a response required to be transmitted in the active communication mode upon the slave node having the response. The slave node monitors arbitration on a bus, and transmits the response subsequent to the ID when the slave node wins the arbitration on the bus between the ID transmitted from the slave node and another information transmitted from another slave node communicably coupled to the master node via the bus based on a result of the monitor. | 04-05-2012 |
20120137034 | COMMUNICATION SYSTEM, MASTER NODE, AND SLAVE NODE - In a node communicably coupled to alternative nodes through a bus, a transmitting unit receives first designation information from an alternative node. When the first designation information designates the node, the transmitting unit successively transmits, on the bus, the first designation information and data. When a request of an active communication occurs in the node, a request unit determines whether to receive a former part of the first identification information indicative of start timing of an active communication mode on the bus. When determining to receive the former part of the first identification information, the request unit transmits, on the bus, collision information at a timing that allows the collision information to collide with a latter part of the first identification information, resulting in rewrite of the first identification information based on bus arbitration, and transmits second designation information meeting the request of the active communication. | 05-31-2012 |
20120314738 | TRANSCEIVER FOR COMMUNICATING SIGNAL ENCODED TO INCLUDE CLOCK INFORMATION - In a transceiver, a clock generator generates a second clock synchronized with a first clock. The second clock has a period corresponding to a duration of one bit of a digital signal. When first transmission data is supplied to the transceiver with being asynchronous to the second clock, a sampling timing generator detects start data of the first transmission data as a start timing, and generates sampling timings based on the first clock in response to the start timing. The sampling timings have intervals each of which is defined to correspond to the period of the second clock. The first sampling timing is spaced from the start timing. A sampling module samples, at each of the sampling timings, the first transmission data, thus generating second transmission data synchronized with the second clock. | 12-13-2012 |
20130034132 | TRANSCEIVER - An encoding circuit encodes a NRZ code into a transmission line code. A decoding circuit decodes the transmission line code into a NRZ code. If an operation-mode specified by a setting signal is a normal-mode, a transmission switching circuit provides transmit-data received from an input terminal to the encoding circuit to output the encoded transmit-data as communication-data from a communication terminal. If the operation-mode is a sleep-mode, the transmission switching circuit outputs the transmit-data received from the input terminal as the communication-data from the communication terminal. If the operation-mode specified by the setting signal is a normal-mode, a reception switching circuit provides the communication-data received from the communication terminal to the decoding circuit to output the decoded communication-data as receive-data from an output terminal. If the operation-mode is a sleep-mode, the reception switching circuit outputs the communication-data received from the communication terminal as the receive-data from the output terminal. | 02-07-2013 |

A device (clock master) can continuously output successive recessive codes to the communication path, in which condition a transceiver can transmit a dominant code by producing an output drive signal which overwrites a part of a recessive code, currently being received from the communication path, to the dominant level. The output drive signal is shaped with a steeper edge slope at a transition from an inactive to an active level than from the active to the inactive level, enabling an increased data transmission rate without increased noise. | 02-06-2014 |
