The 0x000F02C0/0x000F02C1 is actually used as a generic way to set uniforms, regardless of what they represent. 0x000F02C0's parameter represents the ID of the destination GPU register (0x0 is c0, 0x1 is c1 etc). As such, the meaning of the data being sent over is entirely dependant on the shader currently in use.
