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 I
2
C writing operation.
AD[4:0]
Physical address of the stepper motor. Up
to 32 Stepper-motors can theoretically be
connected to the same I
2
C 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
.
