It should be noted that the PD revision is the maximum possible revision supported by the port. This is different from the 2 bit revision set in PD msg headers. The purpose of the 2 bit revision value is to negotiate between Rev 2.X & 3.X spec rev as part of contract negotiation, while this is used for Get_Revision AMS after a contract is in place.

Revision message consists of the following fields: +----------------------------------------------------+ | Header | RMDO | | No. of data objects = 1 | | +----------------------------------------------------+ While RMDO consists of: * B31..28 Revision Major * B27..24 Revision Minor * B23..20 Version Major * B19..16 Version Minor * B15..0 Reserved, shall be set to zero. As per the PD spec ("8.3.3.16.2.1 PR_Give_Revision State"), a request is only expected when an explicit contract is established and the port is in ready state. This AMS is only supported for PD >= 3.0.
