Application Commands
GetFullStatus1
This command is provided to the circuit by the master to
get a complete status of the circuit and of the stepper motor.
Refer to Tables 19 and 20 to see the meaning of the
parameters sent back to the I²C master.
Note: A GetFullStatus1 command will attempt to
reset flags <TW>, <TSD>, <UV2>, <ElDef>,
<StepLoss>, <CPFail>, <OVC1>, <OVC2>, and
<VddReset>.
GetFullStatus1 corresponds to the following I²C command frame:
