LM3560 Datasheet, PDF (25/42 Pages) Texas Instruments – LM3560 Synchronous Boost Flash Driver w/ Dual 1A High-Side Current Sources (2A Total Flash Current)

I²C-COMPATIBLE CHIP ADDRESS
The device address for the LM3560 is 1010011 (0xA7 for read
and 0xA6 for write). After the START condition, the I²C master
sends the 7-bit address followed by an eighth read or write bit
(R/W). R/W = 0 indicates a WRITE and R/W = 1 indicates a
READ. The second byte following the device address selects
the register address to which the data will be written. The third
byte contains the data for the selected register.

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
Register Descriptions
master. The master releases SDA (HIGH) during the 9th clock
pulse (write mode). The LM3560 pulls down SDA during the
9th clock pulse, signifying an acknowledge. An acknowledge
is generated after each byte has been received.
