__STM32F4xx_LL_BUS_H macro

@file stm32f4xx_ll_bus.h @author MCD Application Team 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 Copyright (c) 2017 STMicroelectronics.
