It's the return half of "OSROM", the code that does the business behind
vectored entry into paged ROMs (most often used to point the filing system
vectors into ROM). If you look before it you'll see the corresponding setup

It moves on the Master because you have PHX and PHY rather than having to do
gymnastics with PHA,
