Signals the ending of serial I/O
ISL54105 Device Select Address Write
The first 7 bits of the first byte select the ISL54105 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
ISL54105 Register Data Read(s)
This is the data read from the ISL54105’s configuration register.
Note: The ISL54105’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.
ISL54105 Register Address Write
This sets the initial address of the ISL54105’s configuration
register for subsequent reading.
Ends the previous transaction and starts a new one
ISL54105 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.
