It is possible to count the number of interrupt events occurring within a specific time interval.
The time interval can be entered in the field “ Timer Period” and must be in the range 0 ms
(timer disabled) to 1677 ms.
The relevant interrupt channel must be activated by entering a “1” in the field “Count”.
The start address from which the count results are to be stored is entered in the field “ Count
Address” .
The count results are in the form of a 16-bit value so that 2 bytes are reserved for each
counter. In the example, the count result from interrupt channel 1 would be stored starting at
address 182, and the count result from interrupt channel 2 starting from address 184.
