GAD_EN
1: the high efficient mode
STPOUT
1: step out detected
MONI
1: driver home position
ACB
1: acceleration completed
MACT
1: motor active excluding wait time
0: motor inactive
If the acceleration function is not used, set 1 by step pulse input, and set 0 when speed gets lower than approximately
350pps (pulse interval equivalent to half step).
