Enumeration Type Documentation

cy_en_sar_range_thres_shift_t

enum cy_en_sar_range_thres_shift_t

Configure the lower and upper thresholds for range detection.

The SARSEQ supports range detection to allow for automatic detection of sample values compared to two programmable thresholds without CPU involvement. Range detection is defined by two global thresholds and a condition. The RANGE_LOW value defines the lower threshold and RANGE_HIGH defines the upper threshold of the range.

Range detect is done after averaging, alignment, and sign extension (if applicable). In other words, the thresholds values must have the same data format as the result data. Range detection is always done for all channels scanned. By making RANGE_INTR_MASK=0, the firmware can choose to ignore the range detect interrupt for any channel.

Enumerator
CY_SAR_RANGE_LOW_SHIFT	Shift for setting lower limit of range detection.
CY_SAR_RANGE_HIGH_SHIFT	Shift for setting upper limit of range detection.

cy_en_sar_range_detect_condition_t

enum cy_en_sar_range_detect_condition_t

Configure the condition (below, inside, above, or outside) of the range detection interrupt.

Enumerator
CY_SAR_RANGE_COND_BELOW	Range interrupt detected when result < RANGE_LOW.
CY_SAR_RANGE_COND_INSIDE	Range interrupt detected when RANGE_LOW <= result < RANGE_HIGH.
CY_SAR_RANGE_COND_ABOVE	Range interrupt detected when RANGE_HIGH <= result.
CY_SAR_RANGE_COND_OUTSIDE	Range interrupt detected when result < RANGE_LOW || RANGE_HIGH <= result.
