Bank Select. These two bits are used in Bank index selection. The
relative data delivered over PECI interface and PECI Agent Absent Bit
can be read from the registers below by setting Bank selection. The
relative data delivered over PECI interface can be read in CR EE and CR
EF, and the PECI warning flag can be read in CR E8 bit 7~4.
PECI Speed Select.
