This command allows user to set maximum 10 counters. When the current counter
value reaches the user defined counter value, the respective counter flag in the event
table will be set.
Note:
1. The current counter value starts with 0.
2. The current counter value will not decrement further once it reaches 0.
3. The current counter value will not increment further once it reaches the user defined
counter value.
4. The current counter value will not increment / decrement if the counter is disabled.
5. The current counter value is saved and will not be reset when the power of the device is
cycled.
6. Note that excessive use of counter (e.g. frequent increment / decrement counter value)
may result in overwritten data flash beyond the life cycle.
