| IOSR | Integrator oversampling ratio (averaging length) from Sinc filter will be summed into one output data sample from the integrator. The output data rate from the integrator will be decreased by this number (additional data decimation ratio). This bit can only be modified when DFEN=0 (DFSDM_FLTxCR1) Note: If IOSR = 0, then the Integrator has no effect (Integrator bypass). 0- 255: The length of the Integrator in the range 1 - 256 (IOSR + 1). Defines how many samples |
| FOSR | Sinc filter oversampling ratio (decimation rate) number is also the decimation ratio of the output data rate from filter. This bit can only be modified when DFEN=0 (DFSDM_FLTxCR1) Note: If FOSR = 0, then the filter has no effect (filter bypass). 0 - 1023: Defines the length of the Sinc type filter in the range 1 - 1024 (FOSR = FOSR[9:0] +1).
