    API to transmit data to UART when configured in DMA mode.




      I am working on a project where i need to connect FX3 to the external peripheral using the  UART interface.This project basically uses a direct DMA channel from UART to USB endpoint to read data coming over Rx lines ,as explained in the UsbUart example. But with this  only  the reception part of the data over UART can be achieved. My requirement is that even before the reception of data , the external peripheral needs to be configured . As the UART is opened or configured in DMA mode the API's like CyU3PUartTransmitBytes will not work . So is there any other way or any API that can be used to send data over the Tx lines of UART from CX3  to the peripheral?
