/ * @brief * Wait for ongoing sync of register(s) to low frequency domain to complete. * * @note * This only applies to the Gecko Family, see the reference manual * chapter about Access to Low Energy Peripherals (Asynchronos Registers) * for details. For Tiny Gecko and Giant Gecko, the RTC supports immediate * updates of registers, and will automatically hold the bus until the *

 *   registers that must complete any ongoing synchronization.
