DDFSTRT

Offset: $092 Access: write Chipset: OCS/ECS/AGA

Sets the horizontal bitplane-fetch start comparison.

Bitfields¶

• Bits 7-2: OCS horizontal comparison in colour clocks.

• Bit 1: Additional ECS/AGA comparison precision.

• Bit 0: Ignored.

The sequencer’s state, DMA enables, and fetch width determine the actual transfers; DDFSTOP does not cut off a fetch group already in progress.
