SPI trasmit and receive on rising clock edge

Hello,

The nature of the SPI protocol is that transmit and receive are always done on alternate edges of the clock.

For example, we can have transmission of data on the leading rising clock edge and the reception on the trailing falling clock edge.
Therefore, within one clock cycle, it is possible to transmit and receive to have the full duplex effect.

Regards,
Min Wei
