3.     Device Operation
CLOCK and DATA TRANSITIONS:  The SDA pin is normally pulled high with an external device. Data on the 
SDA pin may change only during SCL low time periods (see Figure 3-3). Data
changes during SCL high periods will indicate a start or stop condition as
defined below.
START CONDITION:   
A high-to-low transition of SDA with SCL high is a start condition which must
precede any other command (see Figure 3-4).
STOP CONDITION:    
A low-to-high transition of SDA with SCL high is a stop condition. After a read
sequence, the stop command will place the device in a standby power mode
(see Figure 3-4).
ACKNOWLEDGE:    
All addresses and data words are serially transmitted to and from the device in
8-bit words. The device sends a zero to acknowledge that it has received each
word. This happens during the ninth clock cycle.
STANDBY MODE:   
The Atmel
?/DIV>
 AT30TS00 features a low-power standby mode which is enabled:
a)   Upon power-up
b)   After the receipt of the STOP bit and the completion of any internal
operations. The temperature sensor must be disabled by the user for low-
power standby mode.
Two-Wire Software Reset:   
After an interruption in protocol, power loss or system reset, any two-wire part
can be reset by following these steps:
a)   Create a start bit condition
b)   Clock nine cycles
c)   Create another start bit followed by stop bit condition as shown below. The
device is ready for next communication after the above steps have been
completed.
