Dimensioning the pull-up resistors (2k4 resistors in Fig. 4-32 depends on
the load capability (current, power dissipation) of the open-collector out-
puts of the control.
Note:
Controlling the stepper interface with differential signals is
preferable to single-channel control as the noise immunity of
differential signals is generally better than with zero-referenced
signals.
