8.2.1 Addressing
8.2.2 Clock and calendar READ or WRITE cycles
8.2 I
Before any data is transmitted on the I
addressed first. The addressing is always carried out with the first byte transmitted after
the start procedure.
The clock and calendar acts as a slave receiver or slave transmitter. The clock signal SCL
is only an input signal but the data signal SDA is a bidirectional line.
The clock and calendar slave address is shown in
