Function LEUART_Enable

bsp/efm32/Libraries/emlib/src/em_leuart.c:345–363

/ * @brief * Enable/disable LEUART receiver and/or transmitter. * * @details * Notice that this function does not do any configuration. Enabling should * normally be done after initialization is done (if not enabled as part * of init). * * @note * Enabling/disabling requires synchronization into the low frequency domain. * If the same register is modified before a previous up

 *   Select status for receiver/transmitter.
