C-bus protocol
After a start condition a valid hardware address has to be sent to a PCF8591 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
2
C-bus characteristics. In the write mode a data transfer is
terminated by sending either a stop condition or the start condition of the next data transfer.
