Enum stm32_hal2::sai::SaiMode

pub enum SaiMode {
    MasterTransmitter = 0,

}

Select Master or Slave mode. Sets xCR1 register, MODE field. The audio subblock can be a transmitter or receiver, in master or slave mode. The master mode means the SCK_x bit clock and the frame synchronization signal are generated from the SAI, whereas in slave mode, they come from another external or internal master. There is a particular case for which the FS signal direction is not directly linked to the master or slave mode definition. In AC’97 protocol, it will be an SAI output even if the SAI (link controller) is set-up to consume the SCK clock (and so to be in Slave mode).

Variants

MasterTransmitter = 0

The SAI delivers the timing signals to the external connected device: The bit clock and the frame synchronization are output on pin SCK_x and FS_x, respectively. Both SCK_x, FS_x and MCLK_x are configured as outputs. If needed, the SAI can also generate a master clock on MCLK_x pin.

MasterReceiver = 1

SlaveTransmitter = 2

The SAI expects to receive timing signals from an external device. If the SAI subblock is configured in asynchronous mode, then SCK_x and FS_x pins are configured as inputs. If the SAI subblock is configured to operate synchronously with another SAI interface or with the second audio subblock, the corresponding SCK_x and FS_x pins are left free to be used as general purpose I/Os.

SlaveReceiver = 3
