6.4.6 Signal function and timing (only MIS23x).
The description below shows how to connect the pulse source when using the pulse and
direction format. Also the timing is shown. Please be aware that if the indicated minimum
timing is not respected the motor may loose some of the step clocks and the position of
the motor will end up being out of synchronism with the pulse generator.
