DFSDM channel 7 data input register
| INDAT0 | Input data for channel y Input parallel channel data to be processed by the digital filter if DATMPX[1:0]=1 or DATMPX[1:0]=2. Data can be written by CPU/DMA (if DATMPX[1:0]=2) or directly by internal ADC (if DATMPX[1:0]=1). If DATPACK[1:0]=0 (standard mode) Channel y data sample is stored into INDAT0[15:0]. If DATPACK[1:0]=1 (interleaved mode) First channel y data sample is stored into INDAT0[15:0]. Second channel y data sample is stored into INDAT1[15:0]. Both samples are read sequentially by DFSDM_FLTx filter as two channel y data samples. If DATPACK[1:0]=2 (dual mode). For even y channels: Channel y data sample is stored into INDAT0[15:0]. For odd y channels: INDAT0[15:0] is write protected. See for more details. INDAT0[15:0] is in the16-bit signed format. |
| INDAT1 | Input data for channel y or channel y+1 Input parallel channel data to be processed by the digital filter if DATMPX[1:0]=1 or DATMPX[1:0]=2. Data can be written by CPU/DMA (if DATMPX[1:0]=2) or directly by internal ADC (if DATMPX[1:0]=1). If DATPACK[1:0]=0 (standard mode) INDAT0[15:0] is write protected (not used for input sample). If DATPACK[1:0]=1 (interleaved mode) Second channel y data sample is stored into INDAT1[15:0]. First channel y data sample is stored into INDAT0[15:0]. Both samples are read sequentially by DFSDM_FLTx filter as two channel y data samples. If DATPACK[1:0]=2 (dual mode). For even y channels: sample in INDAT1[15:0] is automatically copied into INDAT0[15:0] of channel (y+1). For odd y channels: INDAT1[15:0] is write protected. See for more details. INDAT0[15:1] is in the16-bit signed format. |
