Chapter 10 Inter-Integrated Circuit (S08IICV2)
10.4.1.1
When the bus is free, no master device is engaging the bus (SCL and SDA lines are at logical high), a
master may initiate communication by sending a start signal. As shown in
defined as a high-to-low transition of SDA while SCL is high. This signal denotes the beginning of a new
data transfer (each data transfer may contain several bytes of data) and brings all slaves out of their idle
states.
10.4.1.2
The first byte of data transferred immediately after the start signal is the slave address transmitted by the
master. This is a seven-bit calling address followed by a R/W bit. The R/W bit tells the slave the desired
direction of data transfer.
Only the slave with a calling address that matches the one transmitted by the master responds by sending
back an acknowledge bit. This is done by pulling the SDA low at the ninth clock (see
No two slaves in the system may have the same address. If the IIC module is the master, it must not transmit
an address equal to its own slave address. The IIC cannot be master and slave at the same time. However,
if arbitration is lost during an address cycle, the IIC reverts to slave mode and operates correctly even if it
is being addressed by another master.

1 = Read transfer, the slave transmits data to the master.
0 = Write transfer, the master transmits data to the slave.
