Clock on OMAP3530 MCBSP_CLKS from TPS65950 Regulator

Hi,

  On our OMAP3530 based project we have to generate 2.7KHz(2700Hz) clock on MCBSP5. After Gone through the TRM we found that, with MCBSP_CLKS source we can generate Lower clock rate.  On our board we connected MCBSP_CLKS to CLK256FS of TPS65950. We studied TPS65950 data sheet, But, we didn't find any clue about generating clock on CLK256FS pin from TPS65950.

Can any one please guide us to generate clock?

Is there any other way to generate 2.7KHz clock on MCBSP5?

Thank You
