| The groups measure the frame period with interlace off and on, the length of a scanline and of its horizontal blank, the blanking against the GP1(06h) and GP1(07h) ranges, and GPUSTAT bits 13 and 31 line by line. A further group draws in 480-line interlaced mode at four points of a field and reads the frame buffer back to find which rows were written.[^src] The [video timing](/hardware/gpu/video-timing/) and [GPUSTAT](/hardware/gpu/gpustat/) pages describe the registers. | The groups measure the frame period with interlace off and on, the length of a scanline and of its horizontal blank, the blanking against the GP1(06h) and GP1(07h) ranges, and GPUSTAT bits 13 and 31 line by line.
