Address
020E16
When reset
000016
Function
Specify accessing Slice RAM address
Setting possible value R W
00016 to 23716
Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns out to
be indeterminated.
Note : When access to Slice RAM, must be set Slice RAM at first, then use
Slice RAM data control register (021016).
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.

Function
Read out the data of Slice RAM.
