After a start condition a valid hardware address has to be sent to a PCA9691 device. The
read/write bit defines the direction of the following single or multiple byte data transfer. For
the format and the timing of the start condition (S), the stop condition (P) and the
acknowledge bit (A) refer to the I
is terminated by sending either a stop condition or the start condition of the next data
transfer.
