Undocumented PUF-related registers in XAPP1333 sample code

Hello,

I'm working my way through XAPP1333 and its sample code and noticed that the puf_encrypt( ) function in the puf_user_data.c source file invokes a number of register writes to undocumented registers (as in, not included in the online ZYNQ MPSoC US+ register reference found at https://www.xilinx.com/html_docs/registers/ug1087/ug1087-zynq-ultrascale-registers.html). Is there any documentation available from Xilinx that explains what these registers are and how they are to be used?

The addresses in particular that I can't find information for are 0xFFCA4000, 0xFFCA4004, and 0xFFCA0400.

Take care.
