9.2.2.13 Application Parameters Stored in OTP Memory
Except for the physical address AD[3:0] and for bit ADM,
these parameters, although programmed in a non-volatile
memory can still be overridden in RAM by a LIN writing
operation.
AD[6:0]
Physical address of the stepper motor. Up to
128 stepper motors can theoretically be
connected to the same LIN bus.
ADM
Addressing mode bit (see § 9.2.4.5)
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.
