Identifying the part by reading the internal register

VC5505 vs. C5505:

The Design Rev in Die id register will tell you whether it is VC or C.

Design Rev [15:12] at IDEIDR3 at 0x1C43

VC5505: 4

C5505: 0

However, there is no way to tell -10 and -12 by using internal ID.

Please refer to the system user's guide for details.

On my C5504, DIEID3 reads 0x0604 - i.e. DesigRev is 0.

But when using the CCS5 JTAG XDS100 debugger, all DIEID regs read 0x0000, BOTH in the "Registers" tab and when the CPU reads them.

And the "Registers" tab shows wrong info, i.e. it claims that "0000" is a silicon rev. 1.0 while SPRZ310A.pdf tells that Revision Code (on IC top) "A" is silicon rev. 2.0

To further confuse issues, SPRUGH6b.pdf claims that  0000 is silicon revision 2.2 .
