Synchronization at signal N

You can trigger synchronization at signal N at the encoder input either directly or depending
on the status of a digital input.
Single synchronization
The figure below shows an example of single synchronization at signal N (not dependent on
a digital input):
After synchronization is enabled for counting in an upwards direction, the counter is
synchronized at the first signal N. After resetting and setting the control bit (Page 185)
EN_SYNC_UP once again, the counter can be synchronized again.
