Dear KennyT,

Thank you for your reply.

I read the document, but I can't find description about storage primitive(JKFF, JKFFE, LATCH, DLATCH, SRFF, SRFFE, TFF, TFFE).

https://www.intel.com/content/www/us/en/programmable/quartushelp/18.1/hdl/prim/prim_file_srff_d1455e140.htm

A verilog code example is here. What is the role of "prn" pin?
I want to know more detail about these storage primitive.
