SSATE=B_0x0
ADC injected channel 1 offset register
| OFFSET1 | Data offset y for the channel programmed into bits OFFSETy_CH[4:0] These bits are written by software to define the offset y to be subtracted from the raw converted data when converting a channel (can be regular or injected). The channel to which applies the data offset y must be programmed in the bits OFFSETy_CH[4:0]. The conversion result can be read from in the ADC_DR (regular conversion) or from in the ADC_JDRyi registers (injected conversion). When OFFSETy[25:0] bitfield is reset, the offset compensation is disabled. Note: The software is allowed to write these bits only when ADSTART=0 and JADSTART=0 (which ensures that no conversion is ongoing). If several offset (OFFSETy) point to the same channel, only the offset with the lowest x value is considered for the subtraction. Ex: if OFFSET1_CH[4:0]=4 and OFFSET2_CH[4:0]=4, this is OFFSET1[25:0] which is subtracted when converting channel 4. |
| OFFSET1_CH | Channel selection for the Data offset y These bits are written by software to define the channel to which the offset programmed into bits OFFSETy[25:0] will apply. Note: The software is allowed to write these bits only when ADSTART=0 and JADSTART=0 (which ensures that no conversion is ongoing). |
| SSATE | Signed saturation Enable This bit is written by software to enable or disable the Signed saturation feature. This bit can be enabled only for 8-bit and 16-bit data format (see alignment and offset (ADC_DR, ADC_JDRy, OFFSETy, OFFSETy_CH, OVSS, LSHIFT, RSHIFT, SSATE) for details). Note: The software is allowed to write this bit only when ADSTART=0 and JADSTART=0 (which ensures that no conversion is ongoing). 0 (B_0x0): Offset is subtracted maintaining data integrity and extending result size (9-bit and 17-bit signed format). 1 (B_0x1): Offset is subtracted and result is saturated to maintain result size. |
