Table 18: OTP Overwrite Protection
The command used to load the application parameters via the LIN bus in the RAM prior to an OTP Memory programming is
SetMotorParam. This allows for a functional verification before using a
OTP memory byte. A GetOTPparam command issued after each
Note: zapped bits will really be “active” after a GetOTPparam or a ResetToDefault command or after a power-up.
Application parameters stored in OTP Memory
Except for the physical address PA[3:0] these parameters, although programmed in a non-volatile memory can still be overridden in
RAM by a LIN writing operation.

In combination with HW[2:0] it forms the physical address AD[6:0]of the stepper-motor. Up to 128 Stepper-motors can
theoretically be connected to the same LIN bus
