<LOCKBG> can be zapped to disable future zapping,
otherwise any OTP bit at ‘0’ could still be zapped by using
a SetOTPparam command.
the LIN bus in the RAM prior to an OTP Memory
programming is SetMotorParam. 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 verifying the correct byte
zapping.
Note: Zapped bits will become active only after a power
cycle. After programming the LIN bits the power cycle has
to be performed first to guarantee further communication
with the device.
