Where is the SAI_GCR for a STM32G441 described?
In the reference manual RM440 Rev7 that register is missing while the register is defined in the SAI_TypeDef. I only found a description in the F446 RM0390. Are they the same?

Hi @Nickelgrass,
The STM32G4 has only one SAI, so there is no synchronization to another SAIs.
Therefore the GCR register, which defines synchronization, is not present in STM32G4 and the RM0440 is correct.
For that, the SAI_GCR register must be removed in SAI_TypeDef.
