  This example is based on the GD32F527I-EVAL-V1.0 board, it shows SAI_B0 master send and SAI_B1
slave receive communication using DMA mode. After the communication is complete, if the 
receive data equals to the send data, LED3 turn on, if not, LED3 turn off.

  Connect SAI_B0 FS PIN(PE4) to SAI_B1 FS PIN(PF9).
  Connect SAI_B0 SCK PIN(PE5) to SAI_B1 SCK PIN(PF8).
  Connect SAI_B0 SD PIN(PD6) to SAI_B1 SD PIN(PF6).
