- ==============================================================================
- ##### SAI peripheral extension features #####
- ==============================================================================
-
- [..] Comparing to other previous devices, the SAI interface for STM32F446xx
- devices contains the following additional features :
-
- (+) Possibility to be clocked from PLLR
-
- ##### How to use this driver #####
- ==============================================================================
- [..] This driver provides functions to manage several sources to clock SAI
