This register is used to implement the Split Screen feature of the S1D13704. These bits
determine the height (in lines) of Screen 1. On reset this register is set to 0h.
In landscape modes, if this register is programmed with a value, n, where n is less than the
Vertical Panel Size (REG[06h], REG[05h]), then lines 0 to n of the panel contain Screen 1
and lines n+1 to REG[06h], REG[05h] of the panel contain Screen 2. See Figure 8-1:
"Screen-Register Relationship, Split Screen," on page 64. If Split Screen is not desired,
this register must be programmed greater than, or equal to the Vertical Panel Size,
REG[06h] and REG[05h].
In SwivelView modes this register must be programmed greater than, or equal to the Verti-
cal Panel Size, REG[06h] and REG[05h]. See "SwivelView™" on page 79.
