15.4.5.3. Clock Switching

When you use clock switching, you must follow the following requirements:
  • Ensure that there is no activity.
  • Software must disable this module during the frequency switch and re-enable it after the frequency has changed.
  • When clock switching is complete, the software must reconfigure the NAND initialization registers according to the new frequency before triggering any new transactions onto the flash interface.
