PRODUCTION DATA
Figure 7-12 shows that the triangular waveform uses the DAC-X-MARGIN-LOW (FUNCTION-MIN) and DAC-X-MARGIN-HIGH (FUNCTION-MAX) registers for minimum and maximum levels, respectively. The frequency of the waveform depends on the min and max levels, CODE-STEP and SLEW-RATE settings as shown in Equation 8. An external RC load with a time-constant larger than the slew-rate settings can be dominant over the internal frequency calculation. The CODE-STEP-X and SLEW-RATE-X settings are available in the DAC-X-FUNC-CONFIG register. Writing 0b000 to the FUNC-CONFIG-X bit field in the DAC-X-FUNC-CONFIG register selects triangular waveform.
