SNOSCS2D November 2013 – March 2019 LM3697
PRODUCTION DATA.
Every byte on the SDA line must be eight bits long, with the most significant bit (MSB) transferred first. Each byte of data must be followed by an acknowledge bit (ACK). The acknowledge related clock pulse (9th clock pulse) is generated by the master. The master releases SDA (HIGH) during the 9th clock pulse. The LM3697 pulls down SDA during the 9th clock pulse signifying an acknowledge. An acknowledge is generated after each byte has been received.
Table 2 lists the available registers within the LM3697.
