  • High speed overlay of idle I2C bus bandwidth
    Patent number: 9170975
    Abstract: High-speed serial communications between programmable devices connected to an I2C bus that includes a serial clock channel (SCL) and a serial data channel (SDA), having at least a logical low state and a logical high state. The programmable device determines if the SCL channel is idle, indicated by a logical high state. Determining the SCL to be idle, the programmable device holds the SCL to a logical low state. The programmable device operates high-speed serial communications using the SDA channel while holding the SCL to the low logical state. In response to completion of the high-speed communications, the programmable device releases the SCL channel and the SCL channel returns to the logical high state.
