... Clock (SCL), controls the bus access and generates the Start and Stop conditions, while the 24VL024/ 24VL025 works as slave. Both master and slave can operate as transmitter or receiver, but the master device determines which mode is activated. DS22130A-page 6 © 2009 Microchip Technology Inc. ...

... Transmitter must release the SDA line at this point allowing the Receiver to pull the SDA line low to acknowledge the previous eight bits of data. © 2009 Microchip Technology Inc. 24VL024/24VL025 The data on the line must be changed during the low period of the clock signal. There is one bit of data per clock pulse ...
