| int32_t cy_stc_dsadc_dchan_config_t::rangeLowerThreshold |
Lower threshold of the range condition.
Not all conditionals require the lower range - this value will be ignored in that condition.
| int32_t cy_stc_dsadc_dchan_config_t::rangeUpperThreshold |
Upper threshold of the range condition.
Not all conditionals require the upper range - this value will be ignored in that condition.
| cy_en_dsadc_dchan_achan_select_t cy_stc_dsadc_dchan_config_t::achan |

| cy_en_dsadc_dchan_reference_vrefh_t cy_stc_dsadc_dchan_config_t::vrefhSelect |
Reference to use for the ADC VREFH internal input.
| cy_en_dsadc_dchan_reference_vrefl_t cy_stc_dsadc_dchan_config_t::vreflSelect |
Reference to use for the ADC VREFL internal input.
| cy_en_dsadc_aaf_mode_t cy_stc_dsadc_dchan_config_t::aafMode |
Configure the way in which the Anti-Aliasing Filter will be used.
| cy_en_dsadc_averaging_mode_t cy_stc_dsadc_dchan_config_t::averagingMode |
Configure the Averaging mode to use in the Post Processing block.
There are two averaging modes:
| cy_en_dsadc_averaging_samples_t cy_stc_dsadc_dchan_config_t::averagingSamples |
Configure the number of samples to average:
| cy_en_dsadc_dchan_post_processing_range_mode_t cy_stc_dsadc_dchan_config_t::rangeMode |
Enable / Disable the range detection, or configure the range mode for 'Event Count'.
In 'Event Count' mode, the range conditional works as described by the conditional, except that the condition must be met 'rangeCount' times before the interrupt is generated.
| cy_en_dsadc_dchan_post_processing_range_conditional_t cy_stc_dsadc_dchan_config_t::rangeConditional |
Set the Range Condition.
| uint8_t cy_stc_dsadc_dchan_config_t::ppRightShift |
FIR Right Shift.
This right shift lives in the Post Processor, and requires the Post Processor be enabled (it is enabled by default)
| uint8_t cy_stc_dsadc_dchan_config_t::rightShift |
Configure the right shift for values out of the decimator.
Values out of the decimator can more than 32 bits, based on the quantization level, the decimation ratio of the decimator, the decimator left shift, and offset / gain correction values. The minimum value for this should be: val = log2(quantizationLevel) + MAX(LeftShiftNumBits) + N*log2(Stage1DecimationRatio) - 32 Where:
| uint8_t cy_stc_dsadc_dchan_config_t::rateReducerRightShift |
Configure the right shift for values out of the rate reducing (second stage) decimator.
Values out of the rate reducing decimator can more than 32 bits, based on the decimation ratio of the decimator. The minimum value for this should be: val = 2 *log2(Stage2DecimationRatio)
| uint8_t cy_stc_dsadc_dchan_config_t::validGcorBits |
Provides the exponent-1 of the number and limits its precision.
Bits in the significant that are beyond the exponent are ignored. E.g., gcor=0x3, validGcorBits=2 represents the number 0.11b = 0.75 E.g., gcor=0xc, validGcorBits=4 represents the number 0.1100b = 0.75 E.g., gcor=0xc, validGcorBits=2 represents the number 1.00b = 1.0 (gcor bit number 4 is ignored) This value affects the gain correction of the DCHAN and AGC
| uint8_t cy_stc_dsadc_dchan_config_t::rangeCount |
Number of times the conditional must be met before the interrupt is generated.
Requires that 'rangeMode' be configured for CY_DSADC_DCHAN_RANGE_MODE_EVENT_COUNT
| bool cy_stc_dsadc_dchan_config_t::enableGainCorrection |
Enable the gain correction.
