SDK • RP2350: How to enable XIP PSRAM?

I want to enable XIP PSRAM on the RP2350. The CS line is connected to RP47.

As far as I can see I need to set alternate function F9 on GPIO47
I also need to set the memory as writable which I do by setting WRITABLE_M1 in the XIP CTRL register.
Is there anything else I need to do and are there any SDK helper functions to do this?

Thanks
