 TED register #$14

I have a doubt about this register, and I want to update SVS-Ultimate map with a clear and correct info.
Register at $FF14 is used to setup the address of Text screen area (default is $0C00) and by subtract -$0400 the so called "Screen Attributes area".
Ok, but I found referring to this register for using in HR and Bitmap Multicolor mode, to tell TED where is the area of HR screen attributes (default $1800). My question is: it these 2 operations use the same register, what happens when user has a split screen (HR + text)?

When using the split screen (GRAPHIC 2 or 4 mode) the KERNAL interrupt handler does the switching at the specified raster line and switches between graphic mode and changes $ff14 from $18 to $08.
