Bit 0/Extended System Information Bus Enable (ESIEN).
Bits 1 to 3/Output Data Bus Line Select (ESIBSEL0 to ESIBSEL2). These bits tell the device which 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.
Bit 4/Unused, must be set to zero for proper operation.
Bit 5/Unused, must be set to zero for proper operation.
