Fields

DATSRC	Source data for the digital filter This field is set and cleared by software. 0x: Stream coming from the BSMX selected Note: This field can be write-protected (see Section 46.4.13: Register protection for details). 2 (B_0x2): Stream coming from the ADCITF1 selected 3 (B_0x3): Stream coming from the ADCITF2 selected
CICMOD	Select the CIC order This field is set and cleared by software. It is used to select the order of the MCIC. others: reserved Note: This field can be write-protected (see Section 46.4.13: Register protection for details). 4 (B_0x4): MCIC configured in single Sinc⁴ filter 5 (B_0x5): MCIC configured in single Sinc⁵ filter
MCICD	CIC decimation ratio selection This field is set and cleared by software.It is used to select the CIC decimation ratio. A decimation ratio smaller than two is not allowed. The decimation ratio is given by (CICDEC+1). … Note: This field can be write-protected (see Section 46.4.13: Register protection for details). 0 (B_0x0): Decimation ratio is 2. 1 (B_0x1): Decimation ratio is 2.
MCICD8	CIC decimation ratio selection This field is set and cleared by software.It is used to select the CIC decimation ratio. A decimation ratio smaller than two is not allowed. The decimation ratio is given by (CICDEC+1). … Note: This field can be write-protected (see Section 46.4.13: Register protection for details). 0 (B_0x0): Decimation ratio is 2. 1 (B_0x1): Decimation ratio is 2.
SCALE	Scaling factor selection This field is set and cleared by software. It is used to select the gain to be applied at CIC output (see Table 419 for details). If the application attempts to write a new gain value while the previous one is not yet applied, this new gain value is ignored. Reading back this field informs the application on the current gain value. … … others: Reserved 0 (B_0x0): 0 dB 1 (B_0x1): + 3.5 dB 2 (B_0x2): + 6 dB or shift left by 1 bit 24 (B_0x18): + 72 dB or shift left by 12 bits 32 (B_0x20): - 48.2 dB or shift right by 8 bits (default value) 33 (B_0x21): - 44.6 dB 34 (B_0x22): - 42.1 dB or shift right by 7 bits 35 (B_0x23): - 38.6 dB 46 (B_0x2E): -6 dB or shift right by 1 bit 47 (B_0x2F): -2.5 dB
