Note:

Refer to RM0366 Reference Manual I2S Section for more details about the sampling

frequency (Fs), fMCK, fCK, DCK values reflect only the digital peripheral behavior, source

clock precision might slightly change the values DCK depends mainly on ODD bit value.

Digital contribution leads to a min of (I2SDIV/(2*I2SDIV+ODD) and a max

(I2SDIV+ODD)/(2*I2SDIV+ODD) and Fs max supported for each mode/condition.
