Synchronous mode, master/slave mode, transceiver routine:
Master:USART2_CK(PA4)\USART2_Tx(PA2)\USART4_Rx(PA3).
Slave:SPI1_SCK(PA5)\SPI1_MISO(PA6)\SPI1_MOSI(PA7).
This example demonstrates using USART2 as the master and SPI1 as the slave,
sending and receiving data in full duplex.
Hardware connection:PA4 -- PA5
PA2 -- PA7
PA3 -- PA6
