Field Name (ID): Description

SPRITE_D_START:
This field selects the end of the ram used for Sprite C and the start
of the RAM for Sprite D. If sprite C is unused, this field can be set to the same value as
Sprite C START. If Sprite D is unused, this field can be set to TOTALSIZE-1. It must be
programmed to a number greater than or equal to the value in Sprite C START and less
than the total size of the RAM (TOTALSIZE). The size of the Sprite C FIFO will be (Sprite
D START-Sprite C START)*64. The size of the Sprite D FIFO will be (TOTALSIZE-Sprite D
START-1) *64 bytes.
[DevBLC and DevCTG]: Reserved: Write as zero.

RW
SPRITE_CSTART:
This field selects the end of the ram used for display B and the start
of the RAM for Sprite C. If display B is unused, this field can be set to zero. The value
should never exceed the size of the RAM (TOTALSIZE). The size of the display B FIFO
will be (Sprite C START)*64 bytes.

RW
SPRITE_BSTART:
This field selects the end of the ram used for Sprite A and the start
of the RAM for Sprite B. If sprite A is unused, this field can be set to the same value as
Sprite A START. If Sprite B is unused, this field can be set to TOTALSIZE-1. It must be
programmed to a number greater than or equal to the value in Sprite A START and less
than the total size of the RAM (TOTALSIZE). The size of the Sprite A FIFO will be (Sprite
B START-Sprite A START)*64. The size of the Sprite B FIFO will be (TOTALSIZE-Sprite B
START-1) *64 bytes.
[DevBLC and DevCTG]: Reserved: Write as zero.

SPRITE_ASTART:
This field selects the end of the ram used for display A and the start
of the RAM for Sprite A. If display A is unused, this field can be set to zero. The value
should never exceed the size of the RAM (TOTALSIZE). The size of the display A FIFO
will be (Sprite A START)*64 bytes.
