Field Documentation

◆ channelHwEnable

bool cy_stc_sar2_channel_config_t::channelHwEnable

If HW is started, or just configured.

◆ channelPriority

uint8_t cy_stc_sar2_channel_config_t::channelPriority

Channel priority.

0=highest, 7=lowest.

◆ extMuxSelect

uint8_t cy_stc_sar2_channel_config_t::extMuxSelect

External analog mux selection.

◆ extMuxEnable

bool cy_stc_sar2_channel_config_t::extMuxEnable

External analog mux enable.

◆ sampleTime

uint16_t cy_stc_sar2_channel_config_t::sampleTime

Sample time (aperture) in ADC clock cycles.

The minimum is 1 (0 gives the same result as 1), the minimum time needed for the proper settling is at least 300ns, i.e. 6 clock cycles at the max frequency of 20MHz.

◆ averageCount

uint16_t cy_stc_sar2_channel_config_t::averageCount

Averaging count.

Active only if post processing mode is set to Averaging or Averaging + Range detect. The valid range is [1..256]

◆ rightShift

uint8_t cy_stc_sar2_channel_config_t::rightShift

Shift Right.

When using post processing mode with averaging, the set value is used for the right-shift value of the conversion result. Averaging data may be over 12 bits, therefore the user must ensure the conversion result is not to over 12 bits by using this value. This value is also used to fit the 12-bit result in 8 bits. The valid range is [0..15]

◆ positiveReload

uint16_t cy_stc_sar2_channel_config_t::positiveReload

Positive pulse reload value.

Active only if post processing is set to the Pulse detection. The valid range is [0..255].

◆ negativeReload

uint8_t cy_stc_sar2_channel_config_t::negativeReload

Negative pulse reload value.

Active only if post processing is set to the Pulse detection. The valid range is [0..31].

◆ interruptMask

uint32_t cy_stc_sar2_channel_config_t::interruptMask

Select the interrupt sources.
