42. Although not stored in the OTP memory the physical status of the hardware address input pins are returned by a read of the OTP contents.
43. The Ihold0 bit is read as ‘1’ for product version AIMS30621C6217G and AMIS30621C6217RG.
GetStatus
This command is provided to the circuit by the LIN master
to get a quick status (compared to that of GetFullStatus
command) of the circuit and of the stepper−motor. Refer to
Flags Table to see the meaning of the parameters sent to the
LIN master.
Note: A GetStatus command will attempt to reset flags
<TW>, <TSD>, <UV2>, <ElDef>, <StepLoss> and
<VddReset>.
