Enables the exchange of Pdelay (peer-to-peer delay) messages, as a means of measuring Propagation Delay. When this property is true, the port transmits Pdelay request messages (Pdelay_Req) to the neighboring clock and processes received Pdelay response messages (Pdelay_Resp). The port also processes received Pdelay request messages and transmits Pdelay response messages. The Propagation Delay is measured using this message exchange. The Propagation Delay Configured property is not used while Pdelay is enabled. When this property is false, Pdelay messages are not transmitted, and received Pdelay messages are ignored. The false value is useful for in-vehicle applications in which the topology for time synchronization is considered to be part of the vehicle's static design. The Propagation Delay Configured property must be used in order to specify the propagation delay for the port. The read-only Propagation Delay property reflects Propagation Delay Configured.
