ARM7TDMI Version for ADuC7024

From the ARM infocentre in seems there are two versions of the ARM7TDMI, a Rev 4 and 3. Is the ADuC7024 a version 3 based device, as the data sheet references the Technical Reference Manual DDI0029G?

The online Technical Reference Manual and Product Overview are watermarked "superseded" which I take as meaning the processor has been superseded (by Rev 4 covered in TRM r4p1) rather than the documentation.

A section in TRM r4p1 also mentions a Rev 3a version processor which must be yet another version that is distinct from the 3 and r4p1?
