Bit[2] : Restore operate status signal
Note:
In normal, Restore operate time is very short,
so this signal should remain 0.
Bit[3] : LocalReset status signal
Note:
In normal, LocalReset operate time is very
short, so the status signal remain 0.
Bit[4]: Decoder operation status signal
Bit[5]: Encoder operation status signal:
Bit[6]: Dram overflow symbol
Bit[7]: Dram empty symbol

The high 8 bit data, each page is 256×16bit.

Note:
because the 16 bit pointer divide two parts for
read operation, in the reading, the pointer also
operating, so we should notice the carry bit in
reading operation of main control processing.
