The spec mentions there may be a delay until the value written to INIT can be read back due to the synchronization mechanism between the two clock domains. But it does not indicate the exact clock cycles needed. The 5us delay is a test value and seems ok. Without the delay, CCCR.CCE bit may fail to be set and then the initialization fail sometimes when do repeatly up and down.
