HardStop
This command is internally triggered when an electrical
problem is detected in one or both coils, leading to switch
off the H-bridges. If this problem is detected while the
motor is moving, the <StepLoss> flag is raised allowing
warning the Master that steps may have been lost at the
next GetStatus command. The Master for some safety
reasons can also issue a HardStop command.

This command is provided to the circuit by the Master to
reset ActPos and TagPos registers, in order to allow a
positioning for an initialisation of the stepper motor
position.

ResetToDefaults
The Master provides this command to the circuit in order to
reset the whole Slave node into the initial state.
ResetToDefaults will for instance overload the RAM
with the Reset state of the Registers parameters. This is
another way for the Master to initialise a slave node in case
of emergency, or simply to refresh the RAM content.
