I
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
2
stop condition (P) and the acknowledge bit (A) refer to the I
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.
