You can set the input clock sources and the clkena signals for the GCLK and RCLK
network multiplexers through the Quartus II software using the ALTCLKCTRL
megafunction. You can also enable or disable the dedicated external clock output pins
using the ALTCLKCTRL megafunction.
clock control block.
When using the ALTCLKCTRL megafunction to implement dynamic clock source
selection, the inputs from the clock pins feed the inclk[0..1] ports of the multiplexer,
while the PLL outputs feed the inclk[2..3] ports. You can choose from among these
inputs using the CLKSELECT[1..0] signal.
