3.2.2.1. Updating PLL Settings without a System Reset

Updating the PLL settings without a system reset does not reset the clock manager. All clocks transitions gracefully to their boot safe dividers. You can go in and out of boot mode and force the PLLs into bypass without doing a system reset. Software may reset the PLLs and reconfigure the VCO and bring it out of reset. By doing this you can safely update the PLL settings.
