CCS/TMS320F28379D: How to set the sampling frequency for the ADC?

Tool/software: Code Composer Studio

Hi,

I am using the example code "adc_soc_epwm_cpu01" for TMS320F28379D DSP. How can I set the sampling frequency for the ADC? I have found that the following formula is used for doing that.

Tpwm=(TBPRD+1)xTtbclk

In the example code, TBPRD is set to 4096. But what is the value of Ttbclk?
