{
val = (unsigned int) ((ReadRegister(3) & 0x01) << 8) | ReadRegister(2);
++val;
val *= (PanelY / 2);
WriteRegister(8, val & 0xff);
WriteRegister(9, val >> 8);
}
{
//
// On a single panel, Screen 1 was programmed to show all of its
// lines.
// Screen 2 Display Start Address will have no observable effect.
// For convenience, set the screen 2 address to 0.
//
WriteRegister(8, 0);
WriteRegister(9, 0);
}
Consequently Screen 2 will not be seen, and so the
// Write to Screen 1 Display Start Address Register
// Write to Total Display Line Count Reg
// Scrn 1 Disp Line Count Reg (MSB)
