16.3.2. GetFullStatus2
This command is provided to the circuit by the master to get the actual, target and secure position of the stepper motor. Both the actual
and target position are returned in signed two’s complement 16-bit format. Secure position is coded in 10-bit format. According to the
programmed stepping mode the LSBs of ActPos[15:0] and TagPos[15:0] may have no meaning and should be assumed to be ‘0’.
This command also gives additional information concerning stall detection. Refer to Table 18 and Table 19 to see the meaning of the
parameters sent back to the I
