ISL98001 Serial Bus Address Write
This is the 7-bit address of the ISL98001 on the 2-wire bus. The
address is 0x4C if pin 48 is low, 0x4D if pin 48 is high. Shift this
value left to when adding the R/W bit.
Signals the beginning of serial I/O
ISL98001 Register Data Write(s)
This is the data to be written to the ISL98001’s configuration register.
Note: The ISL98001’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.
ISL98001 Register Address Write
This is the address of the ISL98001’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
ISL98001’s Configuration Register sequentially, beginning at
the Register Address written in the previous step.
