TRANSFERRING 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 acknowl-
edge related clock pulse (9th clock pulse) is generated by the
27
master. The master releases SDA (HIGH) during the 9th clock
pulse (write mode). The LM3554 pulls down SDA during the
9th clock pulse, signifying an acknowledge. An acknowledge
is generated after each byte has been received.
