| ##### 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. |
