Signals the beginning of serial I/O
ISL5410xA Register Data Write(s)
This is the data to be written to the ISL5410xA’s configuration
register.
Note: The ISL5410xA’s Configuration Register’s address pointer
auto increments after each data write: repeat this step to write
ISL5410xA Device Select Address Write
The first 7 bits of the first byte select the ISL5410xA on the 2-
wire bus at the address set by the ADDR[6:0} pins. The R/W bit
is a 0, indicating that the next transaction will be a write.
ISL5410xA Register Address Write
This is the address of the ISL5410xA’s configuration register
that the following byte will be written to.
Signals the ending of serial I/O
* The data write step may be repeated to write to the
ISL5410xA’s Configuration Register sequentially, beginning at
the Register Address written in the previous step.
