Describe Counter Reset.

Describe Counter Reset.

• A. An output instruction that zeroes a counter tag's Accumulated value and clears all of its status bits
• B. A timer that resets the counter periodically
• C. An instruction that increments the Preset Value
• D. A command that toggles the Done Bit

Answer: (A)

Counter Reset clears the accumulated count and all status flags for a counter, restarting the count from zero toward the same preset. The accumulated value goes to zero and flags like Done (and other status indicators) are cleared, so the counter can begin counting toward the preset again. It doesn’t change the preset value, isn’t a timer function, and doesn’t toggle the Done bit by itself.
