FIGURE 13. CONFIGURATION REGISTER READ
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. R/W = 0,
indicating next transaction will be a write.

ISL98001 Register Data Read(s)
This is the data read from the ISL98001’s configuration register.
Note: The ISL98001’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.
