- Forced end of drawing: draw end
- Forcibly interrupts the drawing currently being processed.
- Drawing of that frame will be forcibly terminated within approximately 30 clocks after writing data to the register.
- Please specify 0000H for the write data.
- It is not possible to continue drawing something that has already finished drawing.
- If the amount of data to be drawn is large and the drawing does not finish within one frame, use pseudo-drawing continuation to divide it into two or more parts. Use this drawing forced termination function to forcefully terminate drawing in the middle of this pseudo-drawing continuation. For details, refer to " 4.8 Current Processing Table Address Register ".
