Stop data transfer: A change in the state of the data
line from low to high while the clock line is high defines
the STOP condition.
Data valid: The state of the data line represents valid
data when, after a START condition, the data line is sta-
ble for the duration of the high period of the clock signal.
The data on the line can be changed during the low peri-
od of the clock signal. There is one clock pulse per bit of
data. Figures 5 and 6 detail how data transfer is accom-
plished on the 2-wire bus. Depending on the state of the
R/W bit, two types of data transfer are possible.
Each data transfer is initiated with a START condition
and terminated with a STOP condition. The number of
data bytes transferred between START and STOP con-
ditions is not limited and is determined by the master
device. The information is transferred byte-wise and
each receiver acknowledges with a ninth bit.
