FIGURE 7. CONFIGURATION REGISTER READ
ISL98003 Serial Bus Address Write
This is the 7-bit address of the ISL98003 on the 2-wire bus. The
address is 0x98. R/W = 0, indicating next transaction will be a
write.

ISL98003 Register Data Read(s)
This is the data read from the ISL98003’s configuration register.
Note: The ISL98003’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.
