TDA4VM: MCSPI SLAVE MODE

yutai li

Part Number: TDA4VM

Hi TI Support Team

We need use TDA4VM 3x SPI channel, The 2 SPI take as Master and 1 SPI take as Slave.

From datasheet and TRM, the SPI CLK and Data are bi-directional signaling. So please let me know if TDA4 support SPI Slave mode.

Thanks

Thanks, That means TDA4VM support it. But SDK don’t support SPI slave mode? Is it correct?

Are you referring to Linux or RTOS SDK?

I only find current Linux SDK don’t support SPI slave. Is it correct? How about RTOS?

SPI driver in Linux SDK only support Master mode.

SPI driver in RTOS SDK can support both modes.
