1.14. Data Source Controller

This controller handles the source of PR data, either from JTAG or standard data interface.
The JTAG interface takes precedence over the standard PR data interface. For example, whenever JTAG is engaged through command from Intel® Quartus® Prime Programmer tool, the PR data is sourced from the JTAG interface rather than the PR data interface.
