191 - ddfstrt: Horizontal start of display DMA
215 - ddfstrt and ddfstop are best aligned to 64 pixels.
217 first pixel is output, so diwstrt_h = ddfstrt+64+4 if you want to
221 - ddfstop is ddfstrt+#pixels-64.
227 - if ddfstrt < 192, the sprite DMA cycles are all stolen by the bitplane
229 - you really don't want to make ddfstrt < 128, since this will steal DMA
247 - ddfstrt must be aligned to fetchstart (table 1)
249 ddfstrt = ((diwstrt_h-4) & -fetchstart) - prefetch
252 - if fetchstart is smaller than fetchsize, then ddfstrt can a little bit
254 - ddfstop is ddfstrt+ddfsize-fetchsize
257 ddfstrt < 48 -> memory refresh
