Signals the ending of serial I/O
ISL5410x Device Select Address Write
The first 7 bits of the first byte select the ISL54100 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
ISL5410x Register Data Read(s)
This is the data read from the ISL5410x’s configuration register.
Note: The ISL5410x’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.
ISL5410x Register Address Write
This sets the initial address of the ISL5410x’s configuration
register for subsequent reading.
Ends the previous transaction and starts a new one
ISL5410x 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.
