2.2 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.
