uint32_t SAI_InitTypeDef::Mckdiv

Specifies the master clock divider, the parameter will be used if for AudioFrequency the user choice This parameter must be a number between Min_Data = 0 and Max_Data = 63 on STM32L4Rx/STM32L4Sx devices. This parameter must be a number between Min_Data = 0 and Max_Data = 15 on other devices.

Referenced by HAL_SAI_Init().

uint32_t SAI_InitTypeDef::NoDivider

Specifies whether master clock will be divided or not. This parameter can be a value of SAI Block NoDivider

Note:: For STM32L4Rx/STM32L4Sx devices : If bit NOMCK in the SAI_xCR1 register is cleared, the frame length should be aligned to a number equal to a power of 2, from 8 to 256. If bit NOMCK in the SAI_xCR1 register is set, the frame length can take any of the values without constraint. There is no MCLK_x clock which can be output. For other devices : If bit NODIV in the SAI_xCR1 register is cleared, the frame length should be aligned to a number equal to a power of 2, from 8 to 256. If bit NODIV in the SAI_xCR1 register is set, the frame length can take any of the values without constraint since the input clock of the audio block should be equal to the bit clock. There is no MCLK_x clock which can be output.
