Upon reset, the Bt829B initializes to the SPI output, Mode 1 (SPI-1). In this
mode, Bt829B outputs all horizontal and vertical blanking interval pixels, in addi-
tion to the active pixels synchronous with CLKx1 (16-bit mode), or CLKx2 (8-bit
mode). Figure 2-8 illustrates SPI-1 for the Bt829B. The basic timing relationships
remain the same for 16-bit or 8-bit modes. The 16-bit mode uses CLKx1 as the
reference. The 8-bit mode uses CLKx2. Figure 2-9 shows the video timing for
SPI Mode 1.
