The Serial Bus control lines include the SDA (serial data), SCL (serial clock), and A0-A2 (address) pins. The
LM96080 can only operate as a slave. The SCL line only controls the serial interface, all other clock functions
within LM96080 such as the ADC and fan counters are done with a separate asynchronous internal clock.
