    FX#: SPI full-duplex

    ad7922_2725691

      Hi,

      We are trying to configure FX3 as an SPI master to communicate with a PIC33 device setup as an SPI slave. We would like to have full-duplex communication between the master and the slave.  But in register mode, the available firmware APIs CyU3PSpiTransmitWords() and CyU3PSpiReceiveWords() transfer data in only one direction.

      So we would like to know:

      a) Does FX3 support SPI full-duplex communication in register mode ?

      b) If yes, then which is the API to achieve this ?
