Synchronization
Synchronization must be configured before operating the counter module (see parameter Synchroni-
zation with Z). A rising edge of a reference signal at input Z is used
to set the counter to the load value.
Single and periodical synchronization can be chosen:
The following terms have to be considered:
The count operation has been started with the software release.
The control bit for the release of the synchronization (SYNC_REQ) has to be set.
Durin
g the synchronization no period duration measurement is done.
In sing
le synchronization, the period duration measurement starts automatically after the synchro-
nization.
NOTE
In periodical synchronization, a period duration measurement is not possible. In this case fre-
quency measurement has to be used!
