Which items are listed as Counter Instruction Bits/Components?

• A. Instruction Tag
• B. Instruction Tag, Preset Value, Accumulated Value, Done Bit
• C. Preset Value, Accumulated Value, Done Bit
• D. Instruction Tag, Accumulated Value, Done Bit

Answer: (B)

Counter instructions need four pieces of data to operate: the Instruction Tag identifies which counter instance you’re using; the Preset Value is the target count you want to reach; the Accumulated Value shows how many counts have occurred so far; and the Done Bit signals when the counter has reached the preset value. As counting occurs, the accumulated value increments until it equals the preset, at which point the done bit activates and can drive downstream logic. If any of these are missing, the counter can’t function properly: without the tag there’s no reference to a specific counter; without the preset, there’s no defined finish condition; without the accumulated value there’s no way to monitor progress; without the done bit there’s no explicit signal that the counting is complete.
