Abstract: Provided is a communication device, including: a transmission and reception unit that transmits and receives a signal with an other communication device; an error detection unit that detects an occurrence of an error by having the transmission and reception unit receive a preamble specifying a type of data to be transmitted next, and comparing a bit sequence of a signal received following the preamble to a bit sequence that should be transmitted for the type specified for transmission by the preamble; and a conflict avoidance unit that, if the occurrence of an error is detected by the error detection unit, instructs the transmission and reception unit to transmit a clock corresponding to a certain number of bits following the preamble, and then transmit an abort signal giving an instruction to terminate communication partway through.

Abstract: A master includes a transmission and receiving unit that transmits and receives signals to and from a slave, and the transmission and receiving unit receives read data read out from the slave, and typically drives the second bit of a preamble transmitted/received subsequent to the read data. The master can notify the slave that communication is or is not interrupted at some midpoint, on the basis of the second bit of the preamble. The present technology can be applied to a bus IF that communicates pursuant to, for example, the specification of I3C.

Abstract: There is provided a communication apparatus, including: a transmission/reception unit that transmits/receives a signal to/from a different communication apparatus; and a recovery signal transmission instruction unit that instructs the transmission/reception unit to transmit a recovery signal for recovering communication with the different communication apparatus that is out of working order, the recovery signal including at least a first command, the first command prescribing that no processing is to be executed in the different communication apparatus that is in working order.

Abstract: Communication systems and communication control methods are disclosed. In one example, a slave device belonging to a group of devices to which arbitration is applicable sequentially transmits a start bit and a first address including a first bit having a value different from a corresponding first bit of predetermined pattern data. A master device sequentially transmits the start bit and the predetermined pattern data. The master device arbitrates the master device and the first slave device based on the value of the first bit.

Abstract: There is provided a communication apparatus, including: a transmission/reception unit that transmits/receives a signal to/from a different apparatus; a confirmation signal detection unit that detects one of a reception confirmation signal and a non-reception confirmation signal, the reception confirmation signal and the non-reception confirmation signal being transmitted from the different apparatus that has received the signal transmitted from the transmission/reception unit; and a conflict avoiding unit that instructs the transmission/reception unit to transmit an abort signal for instructing to interrupt communication after ignoring a predetermined number of bits following the non-reception confirmation signal when the confirmation signal detection unit has detected the non-reception confirmation signal.

Abstract: A master includes a transmission/reception unit which transmits/receives a signal to/from a slave, and an error detection unit which detects error occurrence by performing parity check to data received by the transmission/reception unit. Then, the error detection unit performs error detection assuming one bit of 2-bit parity included in the data received by the transmission/reception unit as even parity, and the other bit as odd parity. The present technology can be applied to a bus IF which performs communication in compliance with, for example, an I3C standard.

Abstract: When communication with a slave becomes unavailable, a master instructs the slave to release a drive state for a data signal line, by having a transmission/reception unit perform particular driving of a clock signal line. The slave releases the drive state for the data signal line when a counter detects the particular driving of the clock signal line. The present technology can be applied to a bus IF that performs communication compatible with I3C standard, for example.

Abstract: A communication apparatus, a communication method, a program, and a communication system are disclosed. A master has a sending block for sending data to a slave at two bytes per word and a confirmation block for confirming the data to be sent to the slave that includes notification information for recognizing presence or absence of a word having invalid data. The slave has a receiving block for receiving the data sent from the master on a word basis and a recognition block for, if the received word is recognized to have invalid data according to the notification information, avoiding the execution of the processing based on that invalid data. For example, on the basis of a result of the confirmation of the notification information, the invalid data included in the word recognized to have invalid data is masked.
