The ability to reconfigure the PLL in real time is useful in applications that might
operate at multiple frequencies. It is also useful in prototyping environments,
allowing you to sweep PLL output frequencies and adjust the output clock phase
dynamically. For instance, a system generating test patterns is required to generate
and send patterns at 75 or 150 MHz, depending on the requirements of the device
under test. Reconfiguring PLL components in real time allows you to switch between
two such output frequencies in a few microseconds.
You can also use this feature to adjust clock-to-out (t
changing the PLL output clock phase shift. This approach eliminates the need to
regenerate a configuration file with the new PLL settings.
The following PLL components are configurable in real time:

new settings into a serial shift register chain or scan chain. Serial data shifts to the scan
chain via the scandataport, and shift registers are clocked by scanclk. The
maximum scanclk frequency is 100 MHz. After shifting the last bit of data, asserting
the configupdate signal for at least one scanclk clock cycle synchronously
updates the PLL configuration bits with the data in the scan registers.
