Data Sheet
Table 18: OTP Overwrite Protection
Lock bit
Protected bytes
LOCKBT
(factory zapped before delivery)
0x00 to 0x01
LOCKBG
0x00 to 0x07
The command used to load the application parameters via the LIN bus in the RAM prior to an OTP Memory programming is
. This allows for a functional verification before using a SetOTPparam command to program and zap separately one
OTP memory byte. A GetOTPparam command issued after each SetOTPparam command allows to verify the correct byte zapping.
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.
PA[3:0]
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
