Communication device, communication method, program, and communication system

A communication method for a communication device, the method comprising:

• communicating with an external communication device;
• detecting an occurrence of an error in a signal by comparing a first bit sequence following a preamble of the data received to a second bit sequence corresponding to a data type designated by the preamble;
• and
• in a case where the occurrence of an error is detected, causing the transmission and reception circuitry to transmit a clock for a duration corresponding to at least a predetermined number of bits following a preamble.

A communication system, comprising:

• a first communication device, including:
• first transmission and reception circuitry configured to communicate, including transmitting and receiving data via a data signal line and transmitting a clock via a clock signal line, and
• control circuitry configured to
• detect an occurrence of an error in a signal by comparing a first bit sequence following a preamble of the data received to a second bit sequence corresponding to a data type designated by the preamble, and in a case where the occurrence of the error is detected, cause the first transmission and reception circuitry to transmit a clock for a duration corresponding to at least a predetermined number of bits following the preamble;
• and
• a second communication device, including:
• second transmission and reception circuitry configured to communicate with the first communication device, including transmitting and. receiving the data via the data signal line and receiving the clock via the clock signal line,
• wherein the second communication device is configured to transmit the first bit sequence to the first communication device.
