Difficulty: Easy
Correct Answer: clearing
Explanation:
Introduction / Context: Consistent terminology prevents confusion when reading datasheets and communicating design intent. In sequential logic, multiple words may describe the same control action, and knowing the standard synonyms speeds collaboration and troubleshooting.
Given Data / Assumptions:
Concept / Approach: Industry usage treats “reset” and “clear” as near-synonyms when Q is forced LOW. Devices may label the control pin as CLR, RST, or RESET̅ (active-LOW). Therefore, “clearing” is the standard action term corresponding to resetting the device to zero.
Step-by-Step Solution:
Define reset: force Q=0, typically via asynchronous input.Match common synonyms: “clear” ≈ “reset” (to zero).Select “clearing” as the term synonymous with resetting.Verification / Alternative check:
Survey datasheets: pins labeled CLR, /CLR, RST, or /RST perform the reset/clear function.Why Other Options Are Wrong:
breaking / freeing / changing: These do not carry standard, precise meanings in this context.Common Pitfalls:
Confusing “preset” (set to 1) with “reset/clear” (set to 0).Assuming reset is always asynchronous; some designs implement synchronous clear.Final Answer:
clearing
