a: Counter will increment b: Counter will decrement c: Counting stops d: Counter will reset

a: Sets P1 as output b: Clears P1 c: Sets P1 as input d: Increments P1

a: Reads input from P2 b: Outputs the counter value to LEDs c: Resets the counter d: Increments the accumulator

a: It becomes 0x11 b: It resets to 0x00 c: It halts d: It overflows

a: Jump if zero b: Decrease and jump if not zero c: Delay until input d: Divide by zero

a: To start the counter b: To reset the counter c: To toggle the counting direction (UP/DOWN) d: To display output on 7-segment

a: Enables timer interrupt b: Configures INT0 as edge-triggered c: Configures INT0 as level-triggered d: Enables serial communication

a: P0 b: P1 c: P2 d: P3

a: The counter resets to zero b: The counting speed is doubled c: The counting direction is reversed d: The display is refreshed

a: 10 b: 0 c: 8 d: It will stop
