RatedVoltage[7:0] Sets the reference voltage for full-scale output during closed loop operation. The auto
calibration routine uses this register as an input, so this register must be written with the
motor’s rated voltage value before calibration is performed. This register is ignored for
open-loop operation, since the overdrive voltage sets the reference for that case. Any
modification of this register value should be followed by calibration to set ACalBEMF
appropriately.
See "Programming the Rated Voltage" for calculating the correct register value.

ODClamp[7:0] During closed loop operation, the actuator feedback lets the output voltage go above the rated
voltage during the automatic overdrive and automatic braking periods. This register sets a
clamp so that the automatic overdrive is bounded. This also serves as the full scale reference
voltage for open loop operation.
See "Programming the Overdrive Clamp Voltage" for calculating the correct register value.
