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