Serial Start Condition
All commands are preceded by the START condition,
which is a HIGH to LOW transition of SDA while SCL is
HIGH. The device continuously monitors the SDA and
SCL lines for the START condition and does not
respond to any command until this condition has been
met. See Figure 2.
Serial Stop Condition
All communications must be terminated by a STOP
condition, which is a LOW to HIGH transition of SDA
while SCL is HIGH. The STOP condition is also used to
place the device into the Standby power mode after a
read sequence. A STOP condition can only be issued
after the transmitting device has released the bus. See
Figure 2.
Serial Acknowledge
An ACKNOWLEDGE (ACK) is a software convention
used to indicate a successful data transfer. The trans-
mitting device, either master or slave, will release the
bus after transmitting eight bits. During the ninth clock
cycle, the receiver will pull the SDA line LOW to
ACKNOWLEDGE that it received the eight bits of data.
Refer to Figure 3
The device will respond with an ACKNOWLEDGE after
recognition of a START condition if the correct Device
Identifier bits are contained in the Slave Address Byte.
If a write operation is selected, the device will respond
with an ACKNOWLEDGE after the receipt of each sub-
sequent eight bit word.
In the read mode, the device will transmit eight bits of
data, release the SDA line, then monitor the line for an
ACKNOWLEDGE. If an ACKNOWLEDGE is detected
and no STOP condition is generated by the master, the
device will continue to transmit data. The device will ter-
minate further data transmissions if an ACKNOWL-
EDGE is not detected. The master must then issue a
STOP condition to place the device into a known state.
