Part Number: TDA3MV
I have indications that full-duplex SPI communication is only available for SPI1 on the TDA3. Since we would like to use UART3 for bootstrap and this collides with the SPI1 i wonder if this is true. If this is true where in the spruie7d can I find that info?
Thanks in advance
I neither find such restriction in TRM, nor in DataManual and Silicor Errata. I also looked in the PinMux tool and the full-duplex use case is available for all SPIs. Where did you get such indications that SPI2/3/4 can't do full-duplex?

Additionally to Alex's reply:
If you will be using UART3 only for bootstrap, it doesn't mean SPI1 will stay blocked also after boot. I can see only issue with CS0, which is sharing UART3 TX, however CS1, and also (less convenient though) CS2 and CS3 are available for SPI1.
In reply to Alex Bashkov:
Thanks for your information! I think someone at our side has misinterpreted the pinmux tool in that case. I will try to get more information how this assumption was made.
