The SoftStop command causes an immediate deceleration to zero speed and a consequent 
motor stop; the deceleration value used is the one stored in the DEC register (see 

When the motor is in high-impedance state, a SoftStop command forces the bridges to exit 
from high-impedance state; no motion is performed.

This command can be given anytime and is immediately executed. This command keeps 
the BUSY flag low until the motor is stopped.

         

The HardStop command causes an immediate motor stop with infinite deceleration.

When the motor is in high-impedance state, a HardStop command forces the bridges to exit 
from high-impedance state; no motion is performed.

This command can be given anytime and is immediately executed. This command keeps 
the BUSY flag low until the motor is stopped.

         

The SoftHiZ command disables the power bridges (high-impedance state) after 
a deceleration to zero; the deceleration value used is the one stored in the DEC register 
(see 

). When bridges are disabled the HiZ flag is raised.

When the motor is stopped, a SoftHiZ command forces the bridges to enter high-impedance 
state.

This command can be given anytime and is immediately executed. This command keeps 
the BUSY flag low until the motor is stopped.
