TDA4VH-Q1: Whether TDA4 platform support PCIe feature named "Atomic Operation"?

Part Number: TDA4VH-Q1

Hi,

We saw a PCIe feature named "Atomic Operation" in PCIe spec (PCI Express Base Specification, Rev. 4.0 Version 1.0)，with this feature we can perform “read-modify-write” sequence  atomiclly on PCIe mapped memroy. So we want to know if TDA4 platform support this feature? If yes , how can we verify it ?

Thank you.
