Bit Transfer
Each clock pulse transfers 1 data bit. The data on SDA
must remain stable while SCL is high (see Figure 5); oth-
erwise, the device registers a START or STOP condition
(see Figure 6) from the master. SDA and SCL idle high
when the bus is not busy.
START and STOP Conditions
Both SCL and SDA idle high when the bus is not busy.
A master device signals the beginning of a transmission
with a START condition (see Figure 3) by transitioning
SDA from high to low while SCL is high. The master
device issues a STOP condition (see Figure 6) by transi-
tioning SDA from low to high while SCL is high. A STOP
condition frees the bus for another transmission. The bus
remains active if a Repeated START condition is gener-
ated, such as in the block read protocol (see Figure 7).
Early STOP Conditions
The device recognizes a STOP condition at any point
during transmission except if a STOP condition occurs in
the same high pulse as a START condition. This condi-
tion is not a legal I
2
C format. At least one clock pulse
must separate any START and STOP condition.
Repeated START Conditions
A Repeated START (SR) condition may indicate a change
of data direction on the bus. Such a change occurs when
a command word is required to initiate a read operation
(see Figure 4). SR may also be used when the bus mas-
ter is writing to several I
2
C devices and does not want to
relinquish control of the bus. The device serial interface
supports continuous write operations with or without an
SR condition separating them. Continuous read opera-
tions require SR conditions because of the change in
direction of data flow.
