Before any data is transmitted on the I
always carried out with the first byte transmitted after the start procedure.
The clock/calendar acts as a slave receiver or slave transmitter. Therefore the clock signal SCL is only an input signal,
but the data signal SDA is a bidirectional line.
The clock/calendar slave address is shown in Fig.16. Bit A0 corresponds to hardware address pin A0. Connecting this
