Is the formula for the frequency of the sine wave generated by the D / A converter in the document from ST incorrect?

Hi,I generate a sine wave on the DAC. To trigger the DAC, I use the TIM 2 timer, which is clocked on the APB1 (32 MHz) bus, then I reduce its frequency through the dividers PSC = 15 and ARR = 1. In this way, I obtain the frequency from the timer equa...
