Detailed Description

Structure representing a flush command for the PPU (Pixel Processing Unit).

The Flush command ensures that any changes made to VRAM or the palette through drawing commands are fully committed from the cache to the actual VRAM. This operation is known as cache flushing.

Note: Frequent use of the flush command can introduce performance overhead due to the cost of cache flushing. It is recommended to minimize the number of flush operations by grouping drawing commands efficiently. Only flush when necessary, especially when working with palette or VRAM updates.
