HardHiZ

The HardHiZ command immediately disables the power bridges (high impedance state) and

raises the HiZ flag.

When the motor is stopped, a HardHiZ 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.

11.2.20

GetStatus

The GetStatus command returns the Status register value.

The GetStatus command resets the STATUS register warning flags. The command forces

the system to exit from any error state. The GetStatus command DOES NOT reset the HiZ

flag.
