ISL51002 Serial Bus Address Write
This is the 7-bit address of the ISL51002 on the 2-wire bus. The
address is 0x98 if pin 67 is low, 0x9A if pin 67 is high. R/W = 0,
indicating next transaction will be a write.
Signals the beginning of serial I/O
ISL51002 Register Address Write
This sets the initial address of the ISL51002’s configuration
register for subsequent reading.
Ends the previous transaction and starts a new one
ISL51002 Serial Bus Address Write
This is the 7-bit address of the ISL51002 on the 2-wire bus. The
address is 0x98 if pin 67 is low, 0x9A if pin 67 is high. R/W = 1,
indicating next transaction(s) will be a read.
ISL51002 Register Data Read(s)
This is the data read from the ISL51002’s configuration register.
Note: The ISL51002’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.
Signals the ending of serial I/O
