RDP The Graphics Processor

Command Interface

TODO: Complete documentation on the DPC registers

The RDP status register defines bits 9 and 10 as start valid and end value.

I believe 0 represents valid, and 1 represents invalid according the way the graphics ucode uses the start valid bit.

RSP stalls till the start valid value is 0, does that mean RSP is forever stuck or does the RDP eventually mark start valid?
