IMPORTANT
A cycle has to consist of at least two clock duty times and one clock pause
time.
IMPORTANT
The total sum of clock duty times and clock pause times is the duty time. If
the clock duty time and the clock pause time are selected in a way that
their total sum cannot correspond to the duty time, the duty time is auto-
matically rounded up.
Example:
Clock duty time = 5 sec., Clock pause time = 3 sec., selected duty time =
11 sec.
→ The duty time is rounded up to 5+3+5 = 13 sec.
