Question on DAC

Hello

I have a basic question on DAC.

I want to be able to initiate DAC cycles over the PCI bus. I do not want
to support being a target of 64-bit cycles (DAC or otherwise). I assume
that I do NOT need to implement a DAC BAR to be able to achieve this
aim. i.e. the DAC BAR indicates support for DAC target transactions and
does not affect my DAC mastering capability. Are these assumptions
correct?

Thanks in advance

James
