... 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. © 2007 Microchip Technology Inc. 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 ...

... SDA Line Bus Activity © 2007 Microchip Technology Inc. After the word address is sent, the master generates a Start condition following the acknowledge. This terminates the write operation, but not before the internal Address Pointer is set. Then the master issues the control byte again but with the R/W bit set to a one. ...
