Answer 2

Answer:

The RESET pin is used by external devices to obtain control buses.

Therefore, the correct answer is option (1).

Explanation:

All internal activities are paused and the program counter is cleared when the reset pin is engaged by an external key or reset key.

RESET IN- This signal resets the microprocessor by setting the program counter to zero.

RESET OUT- When the microprocessor is reset, this signal is utilized to reset all connected devices.
