Notes
*1: This serial data is only accepted when the IN51/IN52 pulse inputs are in the Low/Low states, respectively. It is
ignored at all other times.
*2: This serial data is only accepted when the IN61/IN62 pulse inputs are in the Low/Low states, respectively. It is
ignored at all other times.
*3: When D4 = 1, MO is only output if microstep mode is selected for channels 3 and 4. In PWM mode, this output is held
fixed at the high level.
*4: The MO output can be specified to be the 1-2 phase position only in 4W1-2 phase excitation mode. In all other
excitation modes, the MO output position becomes the initial position regardless of the serial data values.
