C-bus interface
The I
2
C-bus allows bidirectional data communication
betweendifferentICsormodules.Theserialdatainputline
and serial data output line are connected together, so
representing the Serial Data (SDA) line. See Section 13.4
for layout considerations. The SDA line and the Serial
Clock Line (SCL) line must be connected to a positive
supply voltage via a pull-up resistor. Data transfer may be
initiated only when the bus is not busy.
7.18.1
B
IT TRANSFER
One data bit is transferred during a clock pulse period. The
data on the SDA line must remain stable during the HIGH
period of the clock pulse, otherwise any change in the data
within this period will be interpreted as a control signal
(see Fig.11).
7.18.2
START
AND
STOP
CONDITIONS
Both data and clock lines are HIGH when the bus is not
busy (see Fig.12).
A START condition (S) occurs when the data line goes
from HIGH-to-LOW while the clock is HIGH.
A STOP condition (P) occurs when the data line goes from
LOW-to-HIGH while the clock is HIGH.
