Processor Uncore Configuration Registers
There are four scan chains (1 for each channel and 1 global).
Each chain is broken into smaller “sections”. Each section is composed of N bits where 
N ≤ 32. Each section is used to read/write a particular parameter. Each section contains 
N – 2 data bits (that is, the parameter to be read/written). Each section has two 
additional bits: a Mask bit, and a Halt bit.
