Data Sheet
9.2.2.12 Application Parameters Stored in OTP Memory
Except for the physical address AD[3:0] these parameters,
although programmed in a non-volatile memory can still be
overridden in RAM by a I²C writing operation.
AD[4:0]
Physical address of the stepper motor. Up
to 32 Stepper-motors can theoretically be
connected to the same I²C bus.
Irun[3:0]
Peak current value to be fed to each coil
of the stepper motor. The table to the
right provides the 16 possible values for
IRUN.
Ihold[3:0]
Hold current for each coil of the stepper
motor. The table to the right provides the
16 possible values for IHOLD.
StepMode
Indicator of stepping mode to be used.
