Please could someone post the details to manage the SPI NSS signal? I want to use the SPI as a full-duplex master (sending and receiving data simultaneously). I have read many posts about the NSS deficiencies in the STM32 implementation and I believe that although NSS may be asserted low automatically, it must be cleared high by interrupting on (SPI RX flag ?).

If someone has the detail of how to configure the SPI and make this work, please share. I have read and re-read the latest reference manual and it is still not clear how NSS works. thanks ... John F.
