Interlace display
The display controller can perform both a non-interlace display and an interlace display.
When the DCM register synchronization mode is set to interlace video (11), images in memory are
output in odd and even rasters alternately to each field and one frame (odd + even fields) forms one
screen.
When the DCM register synchronization mode is set to interlace (10), images in memory are output in
raster order. The same image data is output to odd fields and even fields. Consequently, the count of
rasters on the screen is half of that of interlace video. However, unlike the non-interlace mode, there is
a distinction between odd and even fields depending on the phase relationship between the horizontal
and vertical synchronous signals.
