ISL59911 Register Data Write(s)
This is the data to be written to the ISL59911’s Configuration
Register. Note: The ISL59911 Configuration Register’s address
pointer auto-increments after each data write. Repeat this step to
write multiple sequential bytes of data to 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. The
R/W bit is a 0, indicating that the next transaction will be a write.
ISL59911 Register Address Write
This is the address of the ISL59911’s Configuration Register
that the following byte will be written to.
Signals the ending of serial I/O
* The Data Write step can be repeated to write to the
ISL59911’s Configuration Register sequentially, beginning at
the Register Address written in the previous step.
