TMS320F28335: Enquiry about the SPI Master protocol setup, "Write TX data" and "continuous TX data"

Hi JH,

I believe you are asking to clarify "continuous" versus non-continuous transfer of data (please feel free to correct me if I'm wrong)?

The difference between the two would be primarily in the SPIFFCT[TXDLY] bit, which can configure a delay in the transfer of data when using FIFO mode. Adding a delay would result in a non-continuous transfer of words (meaning you would be adding some delay time in between transferring words of data) whereas having no delay would result in a continuous transfer of words. This is further described in the device TRM in section 9.3.7 SPI FIFO Description as well as the register field description in section 9.5.2.11 SPIFFCT Register. Here is a snippet from 9.3.7:

Please let me know if you have further questions or need more help with resolving your SPI receive issue.

Regards,

Allison
