// Update Line Byte Count register for 16 colors/gray shades
//
// Since 16 colors/gray shades corresponds to 2 pixels per byte, there
// are ((x horizontal pixels)/2) bytes per scan line.
// there are ((x horizontal pixels)/4) words per scan line.
//
// Since the Memory Interface is set to 16 bits, the Line Byte/Word Count
// refers to words.
