/* 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.
