2.3.1.2. FPGA-to-HPS Clocks Source

Turning on the Enable FPGA-to-HPS free clock option enables the f2h_free_clk clock input. This is an alternative input to the main HPS PLL driven from the FPGA fabric instead of the dedicated hps_osc_clk pin. Turning on the Enable FPGA-to-HPS free clock option is subject to the same requirements as that pin.
