37.15.2 Switching from (to) Slow Clock Mode to (from) Normal Mode

When switching from Slow Clock mode to Normal mode, the current Slow Clock mode transfer is completed at high clock rate, with the set of Slow Clock mode parameters. See the figure Clock Rate Transition occurs while the SMC is performing a Write Operation. The external device may not be fast enough to support such timings.

The figure Recommended Procedure to Switch from Slow Clock Mode to Normal Mode or from Normal Mode to Slow Clock Mode illustrates the recommended procedure to properly switch from one mode to the other.
