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.
Claims18
A slave device comprising:
- a communication circuitry configured to sequentially transmit a start bit and an address that includes a first bit, the first bit being set to indicate non-inclusion of the slave device in a group for which arbitration is necessary,
- wherein a master device separate from the slave device is configured to transmit a start bit and a predetermined pattern data including a first bit, and
- the master device determines the absence of an event for which arbitration is necessary where the first bit of the address matches the first bit of the predetermined pattern data.
A slave device comprising:
- a communication circuitry configured to sequentially transmit a start bit and an address that includes a first bit, wherein inclusion or non-inclusion in a group for which arbitration is necessary is set according to the first bit,
- wherein a master device separate from the slave device is configured to transmit a start bit and a predetermined pattern including a first bit,
- wherein, when a first bit of the address matches the first bit of the predetermined pattern data an absence of collision is determined, and
- wherein the address of the slave device is allocated by the master device based upon setting information.
A slave device comprising:
- a communication circuitry configured to determine whether a predetermined event has occurred, and to generate a start condition and transmit an address of the slave device upon a determination that the predetermined event has occurred;
- and
- an arbitration circuitry configured to perform arbitration for a collision occurring as a result of generating the start condition and transmitting the address of the slave device.
