/* Split Screen facility */

SPLT is the programmed value. The index denotes the bit number.

VC is the internal CRTC vertical line counter. RC is the internal CRTC raster counter.

~~The value therefore will wrap at 256.~~

Also, during vertical retrace, the value in register 6801h should not be set to 257 less the total number of scan lines on the screen.
