Functional Description and Electrical Characteristics
MISO
• B12 Diagnostic Error: = 1 if OL/SG = 1 or VSHT = 1 or OTMP = 1 (channel specific)
• B11 Command out of Range: = 1 if the average current set point + the hysteresis
setting result in a switch point > 1.23 V or < 0.03 V
• B10 Dither Clipping: = 1 if the dither setting, average current set point, and hysteresis
setting result in a switch point > 1.23 V or < 0.03 V
• B9 - B0 Average Current Set point: Contents of the average current set point
command (non-clipped)
