Nothing is assigned.
When write, set to “0.”
When read, its content is indeterminate.
Note 1 : When access to Slice RAM, Slice RAM address control register (020E16) should be
set at first.
Slice RAM address control register increments by accessing Slice RAM
data control register. So, it is not neccesary to setting the next Slice RAM address.
Note 2 : When read Slice RAM data by software during slicer operation, access to Slice RAM
after 1 horizontal synchronous period from the completion of a SLICEON
(refer to 14.6 Expansion Register Construction Composition for a SLICEON
period).
