/** ****************************************************************************** * @file stm32f1xx_ll_bus.h * @author MCD Application Team * @version V1.1.1 * @date 12-May-2017 * @brief Header file of BUS LL module. @verbatim ##### RCC Limitations ##### ============================================================================== [..] A delay between an RCC peripheral clock enable and the effective peripheral enabling should be taken into account in order to manage the peripheral read/write from/to registers. (+) This delay depends on the peripheral mapping. (++) AHB & APB peripherals, 1 dummy read is necessary [..] Workarounds: (#) For AHB & APB peripherals, a dummy read to the peripheral register has been inserted in each LL_{BUS}_GRP{x}_EnableClock() function. @endverbatim ****************************************************************************** * @attention * *
