A.5 Example
A.5.1. Example of Input Process Image(Input Register) Map
Input image data depends on slot position and expansion slot data type. Input process image data is only ordered
by expansion slot position when input image mode is uncompressed (mode 0, 2). But, when input image mode is
compressed (mode 1, 3), input process image data is ordered by expansion slot position and slot data type.
Input process image mode can be set by special register 0x1114(4372). Refer to 6.3.3.
