pulse. The data on the SDA line must remain stable during the HIGH period of the clock
pulse. Any change in the SDA line at this time will be interpreted as a control signal.
Bit transfer
Acknowledge
The master (µP) puts a resistive HIGH level on the SDA line during the acknowledge clock
pulse (see
the SDA line during the acknowledge clock pulse, so that the SDA line is stable LOW during
this clock pulse. The peripheral which has been addressed has to generate an acknowledge
pulse after the reception of each byte, otherwise the SDA line remains at the HIGH level
during the ninth clock pulse duration. In this case, the master transmitter can generate the
STOP information in order to abort the transfer.
