Command overview

The general construction of a FIFO command is oooo cccc ssss ssss

o is the opcode, which is the general section of commands, and occasionally is all that is needed.

c is the subcommand, which is the operation to be performed selected from the opcode.

s is how many hwords will be pushed to the FIFO in total for this command, including this one.

No Operation

Put Image

D/Z buffer refers to either Display or Z buffer. When WBEN has Z buffer set, the Z buffer is accessed. When it has the display buffer set, it accesses the display buffer.

Subopcode 0010 applies to both D and Z buffer images, depending on the WBEN mode.
