Difference between 65ce02 and 4510 processors?

[fachat]

According to some docs, the C65 used the 4510 processor.

What are the differences to the 65ce02 in terms of processor core?

I understand that the 4510 includes CIA(s) - but what about the instruction set?

@mist64 has written up this http://www.zimmers.net/anonftp/pub/cbm/c65/65ce02.txt

Does this hold true for the 4510 too?

It seems that the 4502 would have been the same, but that the 4510 is slightly different: https://www.devili.iki.fi/Computers/Commodore/C65/System_Specification/Chapter_2/page38.html
