Index 86h
The bits in this register contain second level status reporting. Top level status is reported in F1BAR0+I/O Offset 00h/02h[0].
This register is called a “Mirror” register since an identical register exists at F0 Index F6h. Reading this register does not clear the status,
while reading its counterpart at F0 Index F6h clears the status at both the second and top levels.
