LM96163 REGISTER MAP IN FUNCTIONAL ORDER
The following is a Register Map grouped in Functional Order. Some address locations have been left blank to
maintain compatibility with LM86. Addresses in parenthesis are mirrors of named address. Reading or writing
either address will access the same 8-bit register. The Fan Control and Configuration Registers are listed first, as
there is a required order to setup these registers first and then setup the others. The detailed explanations of
each register will follow the order shown below. POR = Power-On-Reset.
