Hi Stones,

It depends on where exactly you want to implement the SPI access,

is it inside Z-Stak, or you are looking "from a scratch" like solution?

Anyhow, please refer to DN113, it is a good start point.

Hi Igor,

I have read DN113.It only illustrateS how to transmit data with SPI.The datasheet does not explain how to receive data .

Hi Stones,

How come, once SPI finished transmitting data the UxDBUF already contains received data.
