Example of Output Process Image(Output Register) Map
Output image data depends on slot position and expansion slot data type. Output process image data is only
ordered by expansion slot position when output image mode is uncompressed (mode 0). But, when output image
mode is compressed (mode 1), output process image data is ordered by expansion slot position and slot data type.
Output process image mode can be set by special register 0x1115(4373). Refer to 6.3.3.
For example slot configuration
