X24645  
The X24645 will respond with an acknowledge after  
recognition of a start condition and its slave address. If  
Stop Condition  
All communications must be terminated by a stop  
condition, which is a LOW to HIGH transition of SDA  
both the device and a write operation have been  
selected, the X24645 will respond with an acknowledge  
after the receipt of each subsequent 8-bit word.  
when 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.  
In the read mode the X24645 will transmit eight bits of data,  
release the SDA line and monitor the line for an  
acknowledge. If an acknowledge is detected and no stop  
condition is generated by the master, the X24645  
Acknowledge  
Acknowledge is a software convention used to indicate  
successful data transfer. The transmitting device,  
will continue to transmit data. If an acknowledge is not  
detected, the X24645 will terminate further data trans-

that it received the eight bits of data. Refer to Figure 3.
