AMIS-30623 LIN Microstepping Motordriver
Data Sheet
GetFullStatus
This command is provided to the circuit by the LIN master to get a complete status of the circuit and the stepper-motor. Refer to RAM
Registers and Flags Table to see the meaning of the parameters sent to the LIN master.
Note: A GetFullStatus command will attempt to reset flags <TW>, <TSD>, <UV2>, <ElDef>, <StepLoss>, <CPFail>, <OVC1>,
<OVC2> and <VddReset>.
GetFullStatuscorresponds to 2 successive LIN in-frame responses with 0x3D indirect ID.

Important: it is not mandatory for the LIN master to initiate the second in-frame response if ActPos, TagPos and SecPos are not
needed by the application.
