The X24012 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 condi-  
tion, which is a LOW to HIGH transition of SDA when SCL  
both the device and a write operation have been selected,

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 X24012 will transmit eight bits of data,  
release the SDA line and monitor the line for an

Acknowledge is a software convention used to indicate  
successful data transfers. The transmitting device will
