TMS320F280039C: F280039 & ADC161S626

Hi Team,

Here's an issue from the customer may need your help:

The F280039C SPI communicates with the ADC161S626. ADC16S262 needs 18 clocks to complete a data conversion. But the SPI 16-bit data clock has only 16 CLKs.

If SPI CLK is used as the conversion clock of ADC161S626, how to generate 18 CLKs?

Thanks & Regards
