Bit 0/Extended System Information Bus Enable (ESIEN)
Bits 1 to 3/Output Data Bus Line Select (ESIBSEL0 to ESIBSEL2). These bits tell the DS2155 what data bus
bit to output the ESIB data on when one of the ESIB information registers is accessed. Each member of the ESIB
group must have a unique bit selected.
Bits 4 to 7/Unused, must be set to 0 for proper operation
