Hi Yan,

 

Yes, the ADSP-2148x processor have eight independent and synchronous serial ports (SPORTs). According to the Serial Port architecture, it receives serial data on one of its bidirectional serial data signals configured as inputs, or transmits serial data on the bidirectional serial data signals configured as outputs. It can receive or transmit on both channels simultaneously and unidirectionally. The data direction of channel A and channel B on a particular SPORT must be the same. Note that the SPORTx_DA and SPORTx_DB channel data signals on each SPORT cannot transmit and receive data simultaneously for full-duplex operation.

 

For more details can refer to the “Serial Ports (SPORTS)” chapter (546/1304) in the  ADSP-214xx SHARC Processor Hardware Reference manual, it is available via the link given below.

Please let me know if you have further queries

 

Thanks & Regards

Jithul
