Target accesses to registers and DSP memory can go

through any function. As long as the Memory Space access

enable bit is set in that function, then PCI memory accesses

whose addresses match the locations programmed into a

function, BARs 1-3 will be able to read or write any visible

larly, if IO Space access enable is set, then PCI I/O accesses

can be performed via BAR4.

Within the Power Management section of the configuration

blocks, there are a few interactions. The part will stay in the

highest power state between the three configurations.
