PRODUCTION DATA.
The acknowledge symbol must be sent by the receiver during the 9th clock cycle after the transmitter sends a byte of data. The transmitter allows the SDA pin to go high, and the receiver pulls the line low to acknowledge the receipt of the byte (leaving the SDA high indicates that the byte was not received). If this occurs the transmitter issues a STOP and retransmits the message. If the receiver is not prepared to receive another byte, it can suspend transmission by holding the SDA line low during the ACK time slot. When the receiver is ready to receive another byte, it releases the SDA line.
