Table 4-3: Color Registers for Sprite Pairs
SPRITE NUMBERS COLOUR REGISTERS
0 and 1 17-19
2 and 3 21-23
4 and 5 25-27
6 and 7 29-31
NOTE
Some sprites become unusable when additional DMA cycles are allocated to displaying the
screen, e.g. when enabling an extra wide display or horizontal scrolling. (See Figure 6
DMA Time Slot Allocation.)ÿ
SPRITE PRIORITY
When you have more Than one sprite on the screen, you may need to take into
consideration their relative video priority, that is, which sprite appears in front of or
behind another. Each sprite has a fixed video priority with respect to all the others. The
lowest numbered sprite has the highest priority and appears in front of all other sprites;
the highest numbered sprite has the lowest priority. This is illustrated in Figure 4-8.
NOTE
See Chapter 7, "System Control Hardware", for more information on sprite priorities.
