w = write (SDA = “0”)
r = read (SDA = “1”)
ack = acknowledge (SDA pulled down by either master or slave)
rs = repeated start
id = 7-bit chip address, 54H (ADDR_SEL=0) or 55H (ADDR_SEL=1) for LP39542.

C Write Cycle
When a READ function is to be accomplished, a WRITE function must precede the READ function, as shown in the Read Cycle
waveform.
