$P, Q, R, S, X$, and $Y$ are distinct single-digit whole numbers taking values from 0 to 9. $PQ$ is a two-digit number with $Q$ being in the units place and $P$ in the tens place. Similarly, $RS$ is a two-digit number. It is known that $PQ$ and $RS$ are consecutive numbers and $(PQ)^2 + (RS)^2 = XYP$, with $XYP$ being a three-digit number. The value of $Y$ is __________
