ISL51002 Register Data Write(s)
This is the data to be written to the ISL51002’s configuration register.
Note: The ISL51002’s 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.
ISL51002 Register Address Write
This is the address of the ISL51002’s configuration register that
the following byte will be written to.
