Signals the ending of serial I/O
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. R/W = 0,
indicating that the next transaction will be a write.
Signals the beginning of serial I/O
ISL5410xA Register Data Read(s)
This is the data read from the ISL5410xA’s configuration register.
Note: The ISL5410xA’s Configuration Register’s address pointer
auto increments after each data read: repeat this step to read
multiple sequential bytes of data from the Configuration Register.
ISL5410xA Register Address Write
This sets the initial address of the ISL5410xA’s configuration
register for subsequent reading.
Ends the previous transaction and starts a new one
ISL5410xA 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.
