Bits Name
12–31 CM Comparison mask. Contains the size of the translation window. The bits that are 1 in this field indicate bits of
the transaction address that should be matched to the value in the PCI outbound base address register and
translated in case of a match. This field corresponds to the most-significant 20 bits of a 32-bit address.

31 IDLE This read-only bit indicates that the logic controlled by the power management function is idle. This bit could
be used as an indication that it is okay to disable the clocks to this complex.
0 Logic is active.
1 Logic is idle. There are no outstanding transactions in the IOS, the DMA, or the PCI port.
