      5.3.1.4
      Repeated Start Bit
      The Repeated Start bit (see Figure 5-5) indicates the
      current
      master
      device
      wishes
      to
      continue
      communicating with the current slave device without
      releasing the I2C bus. The Repeated Start condition is
      the same as the Start condition, except that the
      Repeated Start bit follows a Start bit (with the Data bits
      + A bit) and not a Stop bit.
      The Start bit is the beginning of a data transfer
      sequence and is defined as the SDA signal falling when
      the SCL signal is “High”.
      FIGURE 5-5:
      Repeat Start Condition
      Waveform.
      5.3.1.5
      Stop Bit
      The Stop bit (see Figure 5-6) Indicates the end of the
      I2C Data Transfer Sequence. The Stop bit is defined as
      the SDA signal rising when the SCL signal is “High”.
      A Stop bit resets the I2C interface of all MCP47X6
      devices.
      FIGURE 5-6:
      Stop Condition Receive or
      Transmit Mode.
      5.3.2
      CLOCK STRETCHING
      “Clock Stretching” is something that the receiving
      Device can do, to allow additional time to “respond” to
      the “data” that has been received.
      The MCP47X6 will not stretch the clock signal (SCL)
      since memory read access occurs fast enough.
      5.3.3
      ABORTING A TRANSMISSION
      If any part of the I2C transmission does not meet the
      command format, it is aborted. This can be intentionally
      accomplished with a Start or Stop condition. This is
      done so that noisy transmissions (usually an extra Start
      or Stop condition) are aborted before they corrupt the
      device.
      FIGURE 5-7:
      Typical 8-Bit I2C Waveform Format.
      FIGURE 5-8:
      I2C Data States and Bit Sequence.
      Note 1: A bus collision during the Repeated Start
      condition occurs if:
       SDA is sampled low when SCL goes
      from low to high.
       SCL goes low before SDA is asserted
      low. This may indicate that another
      master is attempting to transmit a
      data "1".
