more masters devices simultaneously request control of the bus, a clock synchronization
procedure determines the bus clock. Because wire-AND logic is performed on the I2C_SCL line,
a high-to-low transition on the I2C_SCL line affects all the devices connected on the bus. The
devices start counting their low period and once a device’s clock has gone low, it holds the
I2C_SCL line low until the clock high state is reached. However, the change of low to high in this
device clock may not change the state of the I2C_SCL line if another device clock is still within

different mode without releasing the bus. The master transmits data to the slave first, and
then the master reads data from slave by reversing the R/W bit.
