16.3 Application Commands
16.3.1. 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 Table 18
and Table 19 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:
