Example Of Output Process Image(Output Register) Map - Hitachi HX-RIO3 Series User Manual

A.5.2. 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.
