R/W
ISL59911 Register Address Write
This sets the initial address of the ISL59911’s Configuration
Register for subsequent reading.
ISL59911 Serial Bus
START Command
Signals the beginning of serial I/O
ISL59911 Serial Bus Address Write
This is the same 7-bit address that was sent previously, however
the R/W bit is now a 1, indicating that the next transaction(s) will
be a read.

ISL59911 Register Data Read(s)
This is the data read from the ISL59911’s Configuration Register.
Note: The ISL59911 Configuration Register address pointer
auto-increments after each data read: repeat this step to read
multiple sequential bytes of data from the Configuration Register.

ISL59911 Device Select Address Write
The first 7 bits of the first byte select the ISL59911 on the 2-wire
bus at the address set by the ADDR0 and ADDR1 pins.
R/W = 0, indicating that the next transaction will be a write.
