DPA Notification notifies a connected master device at the [N] side that there was a DPA Request without a “read-only” (can be configured by EnableIFacenotificationOnRead) side-effect processed by the [N]. It consists of the same foursome that was part of the original DPA Request except for NADR that stores the address of the sender, not the addressee, and the HWPID that contains the actual HW Profile ID of the device. DPA Notification is therefore always 6 bytes long. DPA Request is considered “read-only” when the corresponding DPA Request returns some data, otherwise, it is considered a “write” request.
DPA Notification is issued to the connected master interface when DPA Request is sent from the [C] or when the DPA Request is part of the FRC acknowledged broadcast (see Acknowledged broadcast - bits and Acknowledged broadcast - bytes).
DPA Notification is not issued in the case of DPA Request invoked from a local interface, from DpaApiLocalRequest, or from predefined FRCs Memory read and Memory read plus 1.
