  This example is based on the GD32450i-EVAL board, it shows SPI1 and SPI3 fullduplex 
communication with ti mode. After the communicate is complete, if receive data equal to 
send data,led1 and led2 turn on. If not, led1 and led2 turn off.

  Connect SPI1 NSS  PIN(PI0) TO SPI3 NSS  PIN(PE11)
  Connect SPI1 SCK  PIN(PI1) TO SPI3 SCK  PIN(PE12)
  Connect SPI1 MISO PIN(PI2) TO SPI3 MISO PIN(PE13)
  Connect SPI1 MOSI PIN(PI3) TO SPI3 MOSI PIN(PE14)
