The chip has two drawing modes. **V1000 compatibility mode** uses ''step'', parallel draw and parameterized draw instructions. **V2000 mode** enables Triangle Engine register shadowing with ''DrawCtl[3:0] = 0xB''. It uses ''tri'' in place of the compatibility draw instructions. [[registers:risc-special:risc_40|DrawCtl]] controls this distinction.
