@verbatim 8 ##### RCC Limitations ##### 9 ============================================================================== 10 [..] 11 A delay between an RCC peripheral clock enable and the effective peripheral 12 enabling should be taken into account in order to manage the peripheral read/write 13 from/to registers. 14 (+) This delay depends on the peripheral mapping. 15 (++) AHB & APB peripherals, 1 dummy read is necessary 16 17 [..] 18 Workarounds: 19 (#) For AHB & APB peripherals, a dummy read to the peripheral register has been 20 inserted in each LL_{BUS}_GRP{x}_EnableClock() function. 21 22 @endverbatim 23 ****************************************************************************** 24 * @attention 25 * 26 * Copyright (c) 2016 STMicroelectronics. 27 * All rights
