Changes
/* Instruction Execution Sequence */
*T2: Get low byte from zero page ($80) then increment the zero page address
*T3: Get high byte from next zero page location ($10) then add the Y register value ($F1) to $1080
*T4: Garbage fetch from memory address $1071 then handle page boundary crossing (since $1080 + $F1 crosses a page)
*T5: Read the value from memory address $1171 into the accumulator then no operation in the last half-cycle
