Boot Cycle Counter
6.8.1 Description
After each start, the current Boot Cycle Counter is read
from the non-volatile memory, incremented by 1 and
rewritten. In addition, a second Boot Cycle Counter is
implemented that can be reset.
The output of the current boot cycle can serve as a control
for the service interval as well as for preventative
maintenance. Schedules for regular maintenance can be
tied to the values of the Boot Cycle Counter.
