(2) during a data transfer, the data line must remain stable whenever the clock line is high. any changes in the data line while the clock line is high will be interpreted as a start or stop condition. start condition the start condition precedes all commands to the device, and is defined as a high to low transition of sda when scl is high. the cat24wc01/02/04/08/16 monitor the sda and scl lines and will not respond until this condition is met. stop condition a low to high transition of sda when scl is high determines the stop condition. all operations must end with a stop condition. device addressing the bus master begins a transmission by sending a start condition. the master then sends the address of the particular slave device it is requesting. the four most significant bits of the 8-bit slave address are fixed as 1010 for the cat24wc01/02/04/08/16 (see fig. 5). the next three significant bits (a2, a1, a0) are the device address bits and define which device or which part of the device the master is accessing. up to eight cat24wc01/ 02, four cat24wc04, two cat24wc08, and one cat24wc16 may be individually addressed by the system. the last bit of the slave address specifies whether a read or write operation is to be performed. when this bit is set to 1, a read operation is selected, and when set to 0, a write operation is selected. after the master sends a start condition and the slave address byte, the cat24wc01/02/04/08/16 monitors the bus and responds with an acknowledge (on the sda line) when its address matches the transmitted slave figure 4. acknowledge timing 5020 fhd f06 acknowledge 1 start scl from master 89 data output from transmitter data output from receiver
