I believe its address is 0x3FF00028 if that helps.
All the other registers seem to be frequently referenced but this one is a bit of a mystery to me at this moment. More specifically I’m interested as to what this does?
#define IOSWAP2HS 6 //Sets Two SPI Masters on HSPI

There is also a reference to the register at:

Thanks in advance.
