EP_AOUT—Must be a high setting value.
Regardless of if the slope is negative or positive of the desired curve, SP must be a low value and
EP must be a high value.
SP position—Position of SP_AOUT value.
EP position—Position of EP_AOUT value.
Example—4.5 V (3 mm) –0.5 V (20 mm) (negative slope). SP_AOUT= 0.5 V, EP_AOUT= 4.5. SP
position= 20, EP position=3.

The following image shows the data format for PWM data.
Figure 12 • Data Format for PWM Data
SP position—Start point position on the data (target position). See the red arrow.
EP position—End point position on the data. See the blue arrow.
SP PWMDuty—Start point PWM duty (for example, 0.9). See the green arrow.
EP PWMDuty—End point PWM duty (for example, 0.1). See the purple arrow.
VIN—N/A.
PWM_Tolerance (duty)—Allowable tolerance for auto calibration.
