                             Sample Description
================================================================================
功能描述：
此样例演示了SPI主机连续接收功能。开启连续接收模式后，SPI硬件自动发送SCK时钟，并接收MISO
端口数据。

Function descriptions:
This sample demonstrates the continuous receiving function of the SPI master. 
After the continuous receiving mode is enabled, the SPI hardware automatically 
sends the SCK clock and receives the data from the MISO port.
